I'm trying to use the compatibility helper createCompatNavigationProp from https://reactnavigation.org/docs/5.x/compatibility/ but I don't know how to use it.
This is the function if it helps: https://github.com/react-navigation/navigation-ex/blob/master/packages/compat/src/createCompatNavigationProp.tsx

Below is the code
require("index/components/" + name); //fails
require("index/components/myComponent"); //work fine
any good solution ?
Dynamic paths in require are not currently supported.
Please check this answer
This is covered in the documentation under the section "Static Resources":
The only allowed way to refer to an image in the bundle is to literally write require('name-of-the-asset') in the source.
You can use a switch statement to implement this.
I'm not sure about it but you can try to write it in ES6
require(`index/components/${name}`);
I want to access child data from server when we append parent. Now I am using
mygrid.attachEvent("onOpenStart", getSubElements );
When I am using getSubElements, this method then it is showing an error: inserNewChild is not a function.
I am using this line, please review this and let me know where I am doing wrong.
mygrid.insertNewChild("a0J9000000TTdLtEAL","a0J9000000TTdKz","CLASS.000010",0,0,0,0,"");
Please note that the insertNewChild() is the method of the dhtmlxTree, and won't work in dhtmlxTreegrid.
http://docs.dhtmlx.com/api__dhtmlxtree_insertnewchild.html
You may use the addRow() method:
http://docs.dhtmlx.com/api__link__dhtmlxtreegrid_addrow.html
Also please try to use the onOpenEnd event instead of onOpenStart:

I am trying to build Esper EPL statements in Java.
I use the com.espertech.esper.client.soda lib for this, but I can't find
a tutorial to help me.
The PatternExpressions are the only part that I need as of now.
As an example let's use the EPL:
every a=Event((a).getEventTypeCode()='E00001')
So he should trigger on every Event with the event type code E00001, we get the code by
calling the getEventTypeCode Method.
How do I project this to SOM?
With:
PatternExpr pattern = Patterns.everyFilter("Event","a");
I only get:
every a=Event
(of course)
I know there is a class called "MethodInvocationStream" but I don't know how to use it.
And I cannot find examples for its use.
Thanks to user650839 I found out how to add Methods via SOM.
Here is a simple EPL as an SOM Object: http://imgur.com/SDrTsa7
One source of info is the javadoc.
You could simply do the reverse and compile EPL text to a model object and inspect that. Use "epAdmin.compileEPL", the output is the same object you want to build via API.\
There is a function GetConfigurationDescriptorPtr, for getting pointer to configuration descriptor, inside IOUSBDeviceInterface. Link for reference is given below.
http://developer.apple.com/library/mac/#documentation/Darwin/Reference/IOKit/IOUSBLib_h/Classes/IOUSBDeviceInterface/index.html#//apple_ref/doc/com/intfm/IOUSBDeviceInterface/GetConfigurationDescriptorPtr
Is there any such function like GetDeviceDecriptorPtr for getting pointer to device descriptor?
Thanks in advance..
There is no such function, but we can create such function when we study the source code of USBProber.
Here is link to download the source code of IOUSBFamily, with USBProber inside it. http://opensource.apple.com/tarballs/IOUSBFamily/

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?
