Hello,

I try to open an editor reflexively with open diagram behavior. Normally
no problem, but in this case I am stuck

!ENTRY org.eclipse.gmf.runtime.diagram.ui 4 4 2010-08-16 15:33:26.731

The providers list List providers = service.getProviders(this,
PRIORITIES[i], operation); computed in ...

/**
* Executes an operation on the first provider of the highest priority
* that provides the operation.
*/
public static final ExecutionStrategy FIRST =
new ExecutionStrategy("First") { //$NON-NLS-1$

private static final long serialVersionUID = 1L;

public List execute(Service service, IOperation operation) {
for (int i = 0; i < PRIORITIES.length; ++i) {
List providers = service.getProviders(this, PRIORITIES[i], operation);

is empty? Any Hints? Aare gmfgen hints missing (validate says the gmfgen
is fine and the source code has also no bugs).

Greetings,

Ralf

Ok. Problem solved. I picked the wrong node in the gmf mapping.

Greetings,

Ralf
