Re: [flexcoders] Activate Component (enable)
A reset button would make it a bit more complicated. Having a data model would
be a recommended solution.
I would start a new thread about the datagrid problem, but basically, Spark
components are not drop-in itemrenderers like MX components.

What seems to work seems pretty involved. I had to bind a variable in the
component and bind one in the main MXML to pass the state (enabled) in.
The next problem I have is probably simpler, but following two matching google
solutions that failed to work means there is probably a depth to this problem
beyond my ignorance.
I just want a check box or radio button to be included in a grid. Both
solutions that I tried looked like this:
dataProvider="{myData}"
selectionMode=! "singleCell"
accessibilityName="Case Composition, DataGrid, use
arrow keys to navigate between cells">
!
!
&n! bsp; &nbs! p;
&! nbsp;
&! nbsp; &nb! sp; ;
It seems straight forward. Add an itemRenderer as the content of a cell. To
enable the control, add a “FX” container. It doesn’t cause any syntax error,
but when you run it you get this:
TypeError: Error #1034: Type Coercion failed: cannot convert
gov.il.dhs.wvs.view.components::UserAA_GridInnerClass0@7cb6cf1 to

Assuming the button and ting you want to enable are in the same MXML file a
typical set up looks like
Even more common is the use of checkboxes for enabling
In which case you can just use binding.

RE: [flexcoders] Activate Component (enable)
BTW, on the itemRenderer problem with the "TypeError: Error #1034: Type Coercion failed"_it would seem that error is a pretty generic one. I say that because in the google search on it not one of the results on the entire first page had anything to do with itemRenderers and in fact seem all unrelated to each other. Just to let you know I do try to find the solution first before I ask others.

RE: [flexcoders] Activate Component (enable)
I think I've found a solution that I'll pass on. UserAA has a bindable Boolean variable that is used to set a property in the component. That property is bound to the enabled property of the container.
