[FlexJS] Code missing in the generated js file?
I am really not sure how flexJS internally works. Is the js code (for example the
file ViewBaseDataBinding.js in org.apache.flex.binding) generated from the
as version (ViewBaseDataBinding.as) from the complier OR is the js file „handwritten“?
Because there is some little difference.
in the ViewBaseDataBinding.js in initCompleteHandler function the following code is missing:
if (!("_bindings" in this._strand))
return;
before the line
var bindingData = this.strand_._bindings;
This is why I get the following error:
Uncaught TypeError: Cannot read property '0' of undefined
org.apache.flex.binding.ViewBaseDataBinding.initCompleteHandler
goog.events.EventTarget.fireListeners
goog.events.EventTarget.dispatchEventInternal_
goog.events.EventTarget.dispatchEvent
childCtor.base
org.apache.flex.events.EventDispatcher.dispatchEvent
org.apache.flex.core.ContainerBase.addedToParent
childCtor.base
org.apache.flex.core.ViewBase.addedToParent
org.apache.flex.core.Application.addElement
org.apache.flex.core.Application.start
(anonymous function)
Thanks

Thanks for the info.
Today, I realized also a small error in the Resize.js. Later I will look if this error is also in the Resize.as and will file a issue in the jira, if this is really a problem.

In FlexJS 0.5.0, many JS files are handwritten. You can tell which ones are handwritten because they have the standard Apache header. Files that were cross-compiled say "Generated by Apache Flex Cross-Compiler from …"
We are just completing the "back port" of all of our JS files to AS, so soon in the nightly build (0.6.0) all JS files will be generated from AS with conditional compilation for SWF-specific or browser-specific code. One advantage of doing that is that more code is shared. I just looked in the back port branch code and that missing check is there for the JS version as well.
So yes, ViewBaseDataBinding.js you are using is handwritten. I guess you must have created an app without any data bindings.
You should be able to monkey-patch FlexJS JavaScript by editing the ViewBaseDataBinding.js in frameworks/js/FlexJS/libs.
Thanks for using FlexJS,
