[Model Focusing Tool]"Not a valid landmark" [message #885237]

Hi,

I'm currently trying the Model Focusing Tool with a gmf diagram (the geoshape example) in order to make a demo tomorrow during Eclipse Democamp Grenoble.

I created a Mylyn local task and activate it.

I have the file correctly added to the context (I see only this file)

When I try to "remove a figure on the diagram from the context" or try to "Mark Model as a landmark", I have an information message dialog with the title "Interest Manipulation" and the message "Not a valid landmark, select an element within this resource instead"

I'm on Juno RC2.
Eclipse Modeling Focusing Tool version: 0.9.0I20120314-1750
Eclipse Mylyn tasks: 3.8.0.I20120605-2216

Do you have any ideas on what is happening?

What is your setup regarding MFT and the geoshape example? MFT currently
doesn't support arbitrary metamodels or GMF editors out of the box.

Did you create a custom StructureBridge for the geoshape model? If so, what
node and edge base classes did you specify?

This indicates that either the wrong StructureBridge was found for the model
element for some reason or that the bridge does not allow this type of model
element to become a landmark.

The exact cause is a bit hard to guess at without knowing what bridges are
active in your runtime.

In your own bridge you could have a look at canBeLandmark(...) and see if it
gets called with the expected element.

You can also figure out which bridge actually gets used in the debugger by
setting a breakpoint in

InteractionContextManager.manipulateInterestForElementHelper(...)

Hi Carsten,

thanks for your answer.

Effectively, I thought that MFT supports arbitrary metamodels or GMF editors out of the box.

So I tried with an .ecorediag and it was working (except during my demo of what's hot in Juno during Eclipse Democamp Grenoble and I don't know why :'()

Thanks again for your clarification.
