Bug 321594

Description Gunnar Schulze 2010-08-03 09:48:53 EDT

Build Identifier: 20100617-1415

In the execute() method of a handler, you can normally retrieve the active editor via HandlerUtil.getActiveEditor(event). However, after displaying e.g. an error dialog, getActiveEditor() returns null. It seems that the activeActionSets variable within the application context gets changed. However, under MacOS X and in versions prior to 3.6 this works.



Reproducible: Always

Steps to Reproduce:
Put the following code into the execute() method of a handler:

public Object execute(ExecutionEvent event) throws ExecutionException
{
    System.out.println("Active editor: " + HandlerUtil.getActiveEditor(event));
    MessageDialog.openError(PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell(), "foo", "bar");
    System.out.println("Active editor: " + HandlerUtil.getActiveEditor(event));
    return null;
}

The active editor can be retrieved before, but not after the execution event.
