DataGrid custom property and item renderers
Can someone verify that the following scenario should work?
Spark DataGrid is extended and has a property test:String.
Two custom item renderers check that property and if it's not set set it.
if (myDataGrid(column.grid.dataGrid).test == "")
myDataGrid(column.grid.dataGrid).test = column.dataField;
What I see is that both columns would have test property empty event though
going thru debugger it's clear that it goes into one renderer then into
another. So, why would second one still has this property not set?
Thanks

No, test value needs to be outside of a renderer.

Why not simply create a ClassFactory for your itemRenderer instead? You
won't require to extend datagrid and just need to create a custom
ItemRenderer.
gridColumn itemRenderer="{customItemRendererFactory}"
being customItemRendererFactory
cf= new ClassFactory(SomeCustomItemRenderer)
cf.properties ={ test: "someValue};
customItemRendererFactory = cf;

More on that. It looks like when I check for test property in prepare
function it's null (expected an empty string) and if I try setting it up to
a value the Expressions window briefly shows "penging" for test value and
then quickly gets back to null. I am not sure I understand what's going on.

I do callLater from prepare to update this property.

In what method do you make the check in the custom itemRenderer ?
