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.

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It could not be published or hold information (Your case #Steve).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;

For handling entities in Drupal I'm using Entity Metadata Wrappers (the "Drupal way").
It's really easy to start coding and see all the advantages it has... except when you get a fatal error and you are not clear where it comes from.
This is what the database log shows:
EntityMetadataWrapperException: Unknown data property
field_whatever. at EntityStructureWrapper->getPropertyInfo()
(line 335 of
/var/www/html/sites/all/modules/entity/includes/entity.wrapper.inc).
Sadly, many times that "field_whatever" is "nid", "uid" or some very common property, so it's name is spread all over my code, which makes me difficult to get to the origin of the error.
I'm currently doing this:
Write a tiny piece of code and then run to see if something fails.
Using getPropertyInfo when handling entities with "not so common" fields.
Loosing hair.
What is worst is that sometimes the error does not appear when you are coding, but a week later. So it could be anywhere...
Is there any way of handling entity metadata wrapper errors better? Can I get better information in the database log and not just a line? A backtrace maybe?
Thanks.
Well, having the devel module active (just to see the nice krumo message) we can do something like this inside our module:
<?php
set_exception_handler('exception_with_trace');
function exception_with_trace($e)
{
dpm($e->getTrace());
}
That will return the backtrace error of the exception thrown by the entity metadata handler on the next page load (some page in your site where everything is running fine).
Also you can set the exception handler exclusively and more elegant just for some pages or some users with some role... or when some parameter in the url is met, or when in some state of your Drupal site is met (ex. when a bool persistent variable 'exception_with_trace' is true). Even, under certain conditions and control, you can use it in production too.
If the site does not work "at all" you can include it in your settings.php file, but instead of printing the trace, you must write the trace to a file and watch the trace in a different context (not Drupal but some php file).
If exceptions are too long and are causing memory problems then getting the trace as string is also possible. See http://php.net/manual/es/exception.gettraceasstring.php
Hope that helps.
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.
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
I have had this same error before and posted a question to that effect but unfortunately there was no answer. The previous error occurred under different circumstances ( ie I was triggered when I used the dojo toolkit sdk(Size 19M).
This time I am retrieving data from a couple of tables which have a one to many relationship. I am using Dojo, Doctrine and Zend Framework for my project. I have posted quite an extensive error message at 1 the Link to pastie.org with code and error details and the php and javascript that I identified as being the code involved.
When you look towards the end of the pastie in the FIREBUG ERROR MESSAGE section you will see a piece of JSON like
[{"id":"000001",
"name":"Adam",
"area_id":null,
"registration_date":"2011-03-08",
"loan_cycle":"0","credit_score":"100",
"created_by":null,
"borrowers":[{"id":"00000001",
"first_name":"Test",
"surname":"User",
"dob":"2006-12-09",
"personalid_no":"100000",
"gender":"Male",
"marital_status":"Marrie",

"status":"Active",
"date_created":null,
"date_registered":"2009-12-11",
"created_by":null,
"Groups_id":"000001"}]
}]
Its clear that the data gets pulled from the tables. However the code fails and I get the error message SyntaxError: missing ) in parenthetical. I have battled with this for a long time now. Am at a point where I either have to abandon the application or restart the whole project again. Thanks for your help.
I have a coworker who's written the following line in the page load method in an aspx page:
myDataSet = (DataSet)HttpContext.Current.Cache["dataset"];
The first time I hit the page HttpContext.Current.Cache["dataset"] reads null. When he does it, the value is "" (string.Empty) and he gets a cast exception.
We're both running ASP.Net 2.0 on our development machines, he's cleared his browser cache and run an iisreset, yet that thing still reads "" the first time he hits the page. Does anyone have ideas on what we can check to explain this discrepancy?
Try this instead for now, you'll at least avoid hitting the exception:
myDataSet = HttpContext.Current.Cache["dataset"] as DataSet;
I'd search your code and see what is actually assigning "dataset" into the cache. Something's got to be putting an empty string in there. Finding that may lead you to some other code that would explain the different results.
Without any real code samples, it's hard to troubleshoot.
Perhaps you should try to use HttpRuntime.Cache instead of the HttpContext.Current.Cache.

Difference between HttpRuntime.Cache and HttpContext.Current.Cache?
