hello,

Instead using a editor, i want to put some figures in a view bu
extending ViewPart.

I have a problem when my editPart runs the method getChildren() (this
method returns a empty list because my model object has no chlidren to
display as a figure within the view). If someone can help me, it would
be very nice because i really don't find any solution...

Here is the error message: an error has occured when activing this view

in my EditPart:

public List getModelChildren()
{
return Collections.EMPTY_LIST;
}

in my viewPart:

public void createPartControl(Composite parent)
{
graphicalViewer = createGraphicalViewer(parent);
}

public GraphicalViewer createGraphicalViewer(Composite parent)
{
ScalableFreeformRootEditPart root = new ScalableFreeformRootEditPart();
GraphicalViewer grapViewer = new ScrollingGraphicalViewer();
grapViewer.createControl(parent);
grapViewer.getControl().setBackground(parent.getBackground() );
grapViewer.setRootEditPart(root);
grapViewer.setEditDomain(new EditDomain());
getSite().setSelectionProvider(grapViewer);
grapViewer.setEditPartFactory(getMyEditPartFactory());
grapViewer.setContents(getContent());

return grapViewer;
}

thank you!

I checked everything i m sure that my model and my editparts are
correctly integrated. But i have aproblem to integrate my gaphicalViewer
within my viewPart. Is someone can help me to do that? Is it different
from the integration with an editorPart?

it seems to work now, but i have again a error message when the view
gets the focus "an error has occured when activing this view". :-(
