cfajaxproxy is sending invalid parameters? - ajax

For some reason that I don't understand, on my development machine can't call to function of a cfc component from a cfajaxproxy.
In my cfm document:
<cfajaxproxy cfc="#Application.CfcPath#.empleado"
jsclassname="ccEmpleado">
This works, and also I can instantiate an object to get all the functions of that cfc component:
var cfcEmpleado = new ccEmpleado();
But, when I try to call a function of that object:
var nb_Empleado = cfcEmpleado.RSEmpeladoNombreBIND(1,1);
Debug complains:
Error: The ID_EMPRESA parameter to the RSEmpeladoNombreBIND function is required but was not passed in.
I got this from Network tab on Chrome and figured out that something is generating an invalid parameter:
http://127.0.0.1/vpa/componentes/empleado.cfc?method=RSEmpeladoNombreBIND&_cf_ajaxproxytoken=[object%20Object]&returnFormat=json&_cf_nodebug=true&_cf_nocache=true&_cf_clientid=41C92098C98042112AE2B3AAF523F289&_cf_rc=0
As you can see, there's a parameter [object%20Object], that is messing around my request, and that's why it fails. I don't why is happening this. Other people has tested this, and it works, but in mine doesn't.
I have Coldfusion 9, Apache, Windows 8. Is is some configuration issue on Coldfusion, or a bug?

I can't tell if this is your error or not, but it might be. This was a problem that we had for awhile. You should consider using explicit names to avoid any confusion. Add the "js" in there.
<cfajaxproxy cfc="cfcEmpleado" jsclassname="proxyEmpleado">
var jsEmpleado = new proxyEmpleado();
I will try to find a link to an article about this very thing.

Meteor 0.5.9: replacement for using Session in a server method?

So, I was attempting to do something like the following:
if(Meteor.isServer){
Meteor.methods({connect_to_api: function(vars){
// get data from remote API
return data;
}});
}
if(Meteor.isClient){
Template.myTpl.content = function(){
Meteor.call('connect_to_api', vars, function(err,data){
Session.set('placeholder', data);
});
return Session.get('placeholder');
};
}
This seemed to be working fine, but, of course, now breaks in 0.5.9 as the Session object has been removed from the server. How in the world do you now create a reactive Template that uses a server-only (stuff we don't want loading on the client) method call and get data back from that Method call. You can't put any Session references in the callback function because it doesn't exist on the server, and I don't know of any other reactive data sources available for this scenario.
I'm pretty new to Meteor, so I'm really trying to pin down best-practices stuff that has the best chance of being future-proof. Apparently the above implementation was not it.
EDIT: To clarify, this is not a problem of when I'm returning from the Template function. This is a problem of Session existing on the server. The above code will generate the following error message on the server:
Exception while invoking method 'connect_to_api' ReferenceError: Session is not defined
at Meteor.methods.connect_to_api (path/to/file.js:#:#)
at _.extend.protocol_handlers.method.exception ... etc etc
Setting the session in the callback seems to work fine, see this project I created on github: https://github.com/jtblin/meteor_session_test. In this example, I return data in a server method, and set it in the session in the callback.
There are 2 issues with your code:
1) Missing closing brace placement in Meteor.methods. The code should be:
Meteor.methods({
connect_to_api: function(vars) {
// get data from remote API
return data;
}
});
2) As explained above, you return the value in the session, before the callback is completed, i.e. before the callback method had the time to set the session variable. I guess this is why you don't see any data in the session variable yet.
I feel like an idiot (not the first time, not the last). Thanks to jtblin for showing me that Session.set does indeed work in the callback, I went back and scoured my Meteor.method function. Turns out there was one spot buried in the code where I was using Session.get which was what was throwing the error. Once I passed that value in from the client rather than trying to get it in the method itself, all was right with the world.
Oh, and you can indeed order things as above without issue.

mvc3 dapper parameter issue

I have dapper working correctly, but it is unsecure as in I haven't been using parameters, how can I best turn my dapper variables into parameters for instance this is the unparameterized code that I had that worked..
var getinfo = sqlConnection.Query<test>("Select name,location from tests where location="+ myplace).FirstOrDefault();
myplace is a textbox that users put information on, now when I tried to parameterized that code like
var getinfo = sqlConnection.Query<test>("Select name,location from tests where location='#location'", new {location = myplace}).FirstOrDefault();
I get absolutely no returns back, yet no error messages. What can I be missing here or whats the best way to parameterized variables.
You do not need to place the single quotes around the parameter. Hope this helps.
var getinfo = sqlConnection.Query<test>("Select name,location from tests where location=#location", new {location = myplace}).FirstOrDefault();

Microsoft AJAX: Unable to get property 'x' of undefined or null reference

How do I troubleshoot the following error being thrown by a Microsoft AJAX JavaScript framework method? It is an automatically generated line of JavaScript from a custom User Control in a Web Forms App (Sitefinity 5 CMS)
Error Message:
Unable to get property 'FancyBlockDesigner' of undefined or null reference
Here is the JavaScript that is throwing the error:
Sys.Application.add_init(function() {
$create(SitefinityWebApp.Esd.TheLab.SampleHtmlEditor.FancyBlockDesigner, null, null, {"Editor":"propertyEditor_ctl00_ctl00_ctl00_ctl00_ctl00_Editor","propertyEditor":"propertyEditor"}, $get("propertyEditor_ctl00_ctl00_ctl00"));
});
Rather than discuss the ascx and cs files that try to abstract this detail away from me, I want to know what this error means. If I understand the detail, the abstraction might make more sense.
"$create" function in ASP.NET Ajax creates an instance of JavaScript class. Microsoft had their own opinion on how to make JavaScript object orientated and as time had shown, their approach wasn't exactly perfect.
Anyhow, to try to explain what is happening, let me give a bit of an overview oh how it works. We start by a server side control which implements IScriptControl interface which mandates two members: GetScriptDescriptors and GetScriptReferences. The second one is pretty straightforward - it lets you register references to all JavaScript files that you control will require. The GetScriptDescriptors, on the other hand, let's you define all the instances of JavaScript classes you want to use as well as it lets you set their properties - initialize them, if you will.
What the autogenerated JavaScript code you've pasted says is basically that you have defined in GetScriptDescriptors that you will need an instance of type "SitefinityWebApp.Esd.TheLab.SampleHtmlEditor.FancyBlockDesigner" where you want Editor property to be initialized. This code will go and look for a JavaScript constructor that looks like this:
function SitefinityWebApp.Esd.TheLab.SampleHtmlEditor.FancyBlockDesigner(element) {
}
that most probably also has a prototype defined, something like:
SitefinityWebApp.Esd.TheLab.SampleHtmlEditor.FancyBlockDesigner.prototype = {
}
Now, since the error you have posted states: "Unable to get property 'FancyBlockDesigner' of undefined or null reference", most probably one of the following is the problem:
You have not included the JavaScript file which contains the class (constructor + prototype) that I've talked about above
You have forgot to add the "FancyBlockDesigner" to the constructor (it seems that you do have other object, perhaps through MS Ajax namespaces - "SitefinityWebApp.Esd.TheLab"
You have not registerd the "SampleHtmlEditor" namespace. Make sure at the top of your JS file you have this: Type.registerNamespace("SitefinityWebApp.Esd.TheLab.SampleHtmlEditor");
So, short story long, the function with name "SitefinityWebApp.Esd.TheLab.SampleHtmlEditor.FancyBlockDesigner" cannot be found.
Hope this helps,
Ivan

ClientGlobalContext.js.aspx broken in Dynamics 2011?

I am trying to implement a custom web resource using jquery/ajax and odata. I ran into trouble and eventually found that when I call:
var serverUrl = context.getServerUrl();
The code throws exceptions.
However, when I change serverUrl to the literal url, it works. I then found forum posts that said I should verify my .aspx page manually by going to https://[org url]//WebResources/ClientGlobalContext.js.aspx to verify that it is working. When I did that I received a warning page:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
--------------------------------------------------------------------------------
Invalid at the top level of the document. Error processing resource 'https://[org url]//WebResources/Clien...
document.write('<script type="text/javascript" src="'+'\x26\x2347\x3b_common\x26\x2347\x3bglobal.ashx\x26\x2363\x3bver\x2...
What the heck does that mean?
Hard to tell outside of context (pun not intended) of your code, but why aren't you doing this?
var serverUrl = Xrm.Page.context.getServerUrl();
(Presumably, because you have defined your own context var?)
Also, this method is deprecated as of Rollup 12, see here: http://msdn.microsoft.com/en-us/library/d7d0b052-abca-4f81-9b86-0b9dc5e62a66. You can now use getClientUrl instead.
I now it is late but hope this will be useful for other people who will face this problem.
Until nowadays even with R15 there are two available ClientGlobalContext.js.aspx
https://[org url]/WebResources/ClientGlobalContext.js.aspx (the bad one)
https://[org url]/[organization name]/[publication id]/WebResources/ClientGlobalContext.js.aspx (The good one)
I don't know why exist 1. but it causes many issues like:
It could not be published or hold information (Your case #Steve).
In a deployment with multiple organizations, seems it saves info only for the last organization deployed causing that methods under Xrm.Page.context. will return info from a fixed organization. Actually each method that underground uses these constants included in ClientGlobalContext.js.aspx: USER_GUID, ORG_LANGUAGE_CODE, ORG_UNIQUE_NAME, SERVER_URL, USER_LANGUAGE_CODE, USER_ROLES, CRM2007_WEBSERVICE_NS, CRM2007_CORETYPES_NS, AUTHENTICATION_TYPE, CURRENT_THEME_TYPE, CURRENT_WEB_THEME, IS_OUTLOOK_CLIENT, IS_OUTLOOK_LAPTOP_CLIENT, IS_OUTLOOK_14_CLIENT, IS_ONLINE, LOCID_UNRECOGNIZE_DOTC, EDIT_PRELOAD, WEB_SERVER_HOST, WEB_SERVER_PORT, IS_PATHBASEDURLS, LOCID_UNRECOGNIZE_DOTC, EDIT_PRELOAD, WEB_RESOURCE_ORG_VERSION_NUMBER, YAMMER_IS_INSTALLED, YAMMER_IS_CONFIGURED_FOR_ORG, YAMMER_APP_ID, YAMMER_NETWORK_NAME, YAMMER_GROUP_ID, YAMMER_TOKEN_EXPIRED, YAMMER_IS_CONFIGURED_FOR_USER, YAMMER_HAS_CONFIGURE_PRIVILEGE, YAMMER_POST_METHOD. For instance method Xrm.Page.context.getUserId() is implemented as return window.USER_GUID;

Cache won't work in Appcelerator

Titanium SDK version: 1.6.
iPhone SDK version: 4.2
I am trying out the cache snippet found on the Appcelerator forum but I get an error: [ERROR] Script Error = Can't find variable: utils at cache.js (line 9).
I put this one (http://pastie.org/1541768) in a file called cache.js and implemented the code from this one (http://pastie.org/pastes/1541787) in the calling script, but I get the error.
What is wrong? I copied the code exactly.
Your problems is whilst the first pastie defines utils.httpcache. The variable utils is not defined outside of this function closure (because it is not defined anywhere in global namespace). As below shows.
(function() {
utils.httpcache = {
};
})();
To make it all work in this instance add the following code to the top of your cache.js file.
var utils = {};
This declares the utils variable in global namespace. Then when the function closure is executed below it will add utils.httpcache to the utils object.
The problem is actually not specific to Appcelerator and is just a simple JavaScript bug. Checkout Douglas Crockfords book, JavaScript the Good Parts. Reading it will literally make you a more awesome JavaScript developer.
You can't use utils.httpcache.getFromCache(url) until you add this to your code:
var utils = {};
That's because how the author created his function, it's called JavaScript module pattern and it's generally used to structure the code.
I seem to lose this value "value.httpCacheExpire = expireTime;" when the code does the "Titanium.App.Properties.setString(key,JSON.stringify(value));" so when I get it back using the getString method, there's no longer the "value.httpCacheExpire.
Anyone else have this issue? Am I missing something to get this working?
