Sorry, this is not duplicate of 37142.

The code in BaseJspEditor, which extends CloneableEditor, is:

getEditorPane().addCaretListener(caretListener);

The method getEditorPane returns pane from CloneableEditor, but the
pane is null.

Giving it back to Peter, it looks like it's his problem 

Fixed in [trunk]

just hot fix:
core/windows/../PersistenceHandler.java 1.3


Problem: There was fired from TC.Registry event about activated TC,
even there was not shown the winsys on the screen (thus the TC was not
inited yet). That event is there so the Registry get the activated
nodes after startup.

Solution: There needs to be considered when exactly the first
activation event should be fired. From this case it seem immediatelly
after the winsys is shown, but I guess it made another problems (like
after init of properties window content).

I did small workaround in the jsp module:

protected void componentActivated() {
            // Workaround for bug #37188. If the pane is null, don't
activate the component.
            if (getEditorPane() != null){
                getEditorPane().addCaretListener(caretListener);
                super.componentActivated();
            }
        }
