Thiago,
Are you saying the I can use <t:grid ... overrides="prop:xyz"> to get around
the problem? Do I just build a list of PropertyOverrides in the page class for
that, and does it override all other overrides that the grid normally provides
by itself - I'm guessing this behavior is not what I want as I just want to
affect rendering for this specific field, < <t:myCustomComponent
value="bom.property"/>?
I had started creating my own PropertyEditContext in the component used for my
custom type <just in the scenario where it's used in a grid>, but was running
into issues with an internal null pointer when I got to validate.render() in my
component's beginRender method.
What I was trying to do was something along the lines of:
boolean pECForGridRequired =
(environment.peek(PropertyEditContext.class) == null);
PropertyEditContext pECForGrid = null;
if (pECForGridRequired){
pECForGrid = createPECForGrid();
environment.push(PropertyEditContext.class, pECForGrid);
}
... and mimicking the way the PEC is created when the component is used in a
beanEditForm. Is this approach wrong-headed?
Regards,
Jim.

I was talking about creating a component that does that, not using this
functionality. :)
By the way, I just remembered about the overrides parameter in Grid.
You'll probably don't need to create another component, just make sure the
overrides provide the edition block instead of the viewing one. Maybe we
could even add a PropertyOverrides implementation that implements that to
Tapestry . . .
