Tool Control needs part access [message #1699682]

Hello,

I have a problem with a tool control in a part with a TableView. The toolcontrol contains a textfield which should update the tableview.
That's why I need to notify the part.

In a former e4 swt app this works fine: I accesed the Part implementation in the control through: MPart.getObject().
But now in e(fx)clipse this is null.

Then I tried to set in the part the filter object in the context:
eclipseContext.set(FilterContainer.class, filter);

But the inject in the toolcontrol delivers also null.

Then I realized that the Toolcontrol class is created after the Part class. That does not seem to be the case in e4 SWT.

OK, as workaround I could send the text through IEventBroker but the FilterContainer would also be nice for init and model update.

I use e(fx)clipse 2.0 nightly.

Thanks
Sebastian

Hi,

so the toolcontrol is part of the MParts Toolbar? I just tried that and
for me things work just file!

Please provide a reproduceable sample so that we can look into it.

Yes, if getObject() is later (Action) called, I get the part.
But not, when it is called immediately in the constructor.
void init(MPart part, Group g) {
System.err.println("========> " +part.getObject());
Button e = new Button("Hello");

But this is most likely no error because the JavaDoc says:
"This is the DI created instance of the class implementing the logic for the element.
It will only be non-null if the element has been rendered into the presentation."

Sorry, my mistake.

with swt renderer the object is already in the constr. set, but that must not be the case according to JavaDoc, I think.

I can solve my problem otherwise, also the little problem that eclipseContext.set(FilterContainer.class, filter); setted in part, is not available in ToolControl Field or constructor inject.
