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'm sorry. I wasn't clear. I want the button to enable a component (or
disable it in the case of the reset button). The component is in the
same MXML file.
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:
cust:MyAdvancedDataGrid
id=dgData
width=100% height=85%
textAlign=center
fontWeight=normal
dataProvider={myData}
selectionMode=singleCell
accessibilityName=Case Composition, DataGrid,
use arrow keys to navigate between cells
cust:columns
mx:AdvancedDataGridColumn
headerText=Select
rendererIsEditor=true
width=100
mx:itemRenderer
fx:Component
s:CheckBox
selected=false/
/fx:Component
/mx:itemRenderer
/mx:AdvancedDataGridColumn
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
mx:Button label=enable text search click=criteria.enabled = true /
mx:TextInput id=criteria enabled=false /
Even more common is the use of checkboxes for enabling
mx:CheckBox label=enable text search id=enableTextSearch /
mx:TextInput enabled={enableTextSearch.selected} /
In which case you can just use binding.

Why wouldn't you set enabled=true on the button click
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.

[flexcoders] Activate Component (enable)
I have a form that includes a component. The form includes selection criteria and a search button. When the user clicks the search button, I want to enable the component and populate a grid of the results of the search. Taking baby steps, the first thing I want to do is the enabling. Search Results Select office: SelectNameCase Office Select case: [ ]x x x Select from date: [ ]y y y Select to date: [ ]z z z Search Btn Details Start EndStuff More Stuff 1 1 1 1 2 2 2 2 The results and details sections (in same component) are disabled until a user selects stuff. Step one is to enable the component when the search button is clicked and all the edit checks are passed. I was thinking of passing a boolean in the component bound to a variable that is defaulted to false and set to true in the search button code, but that didn't work. I couldn't find a property of the component that could be set in the search button click event. TIA, Jerry

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.
