		<description>Hey Jon, thanks for this excellent shortcut for two way binding. I&#039;ve actually gone and replaced a significant amount of code with it, which has made my projects more readable

I did have questions on the dates and combobx binding. Others seem to have it working, but mine are flailing. When bound to dateFields the binding seems to be one-way still, when bound to the selectedDate property.

Which comboboxes It doesnt seem to work at all unless I am using and array of strings as the dataProvider. If I have an ArrayCollection or Array of objects nothing seems to allow it to bind. Any suggestions?

Also, this component doesn&#039;t seem to support binding of properties of nested objects, for example user.pet.petName to petName.text.

Lastly, I noticed that you have a grassroots project going on, stubmatic. I am working on a project that I believe would be complimentary to yours, we should talk :D

		<description>Very usefull ! thanx for sharing !
It seems that two way binding is a common issue, I&#039;ve found this on the net :
http://bugs.adobe.com/jira/browse/SDK-11193
and the adobe solution (available in flex 4 ???)
http://opensource.adobe.com/wiki/display/flexsdk/Two-way+Data+Binding

To come back to your solution, in my opinion the main drawback is that we are loosing the error warning during compilation time :
For example if I introduce a wrong field name I&#039;ll not be warned :


But with this, even if it takes 2 lines, I&#039;ll be warned during compile time



Another issue with binding is the type conversion, for example between an int type of your object model and the String type of the TextInput : how do you handle this issue, do you have any tips ?

Thanx</description>
