Huh? This is in an editor plugin, right? You can't call createPartControl().
It gets called by the framework.

What's your hurry? The viewer isn't editable before it is created. Just set

I understand what you are saying but I invoke setEditable method after the
editor is created,then according to what you are saying I should have the
viewer(I Think).
What actually happens is that I open up the editor frist then through the
Dialog I invoke this method.So if the editor has been opened up then there
should be a viewer.I tried to do the same for retriving text from the
editor and I was having the same problem then.
Or am I missing something here.
Thanks for all your help

Notwithstanding Andrew's response, I believe the source viewer is not
available until after createPartControl() has been called. If you are trying
to get it beforehand, you can solve your problem with a hack like this:
private Boolean deferSetEditable = null;
public void setEditable(boolean editable) {
ISourceViewer viewer = getSourceViewer();
if (viewer != null)
viewer.setEditable(editable);
else
deferSetEditable = editable ? Boolean.TRUE : Boolean.FALSE;
}
public void createPartControl(Composite parent) {
super.createPartControl(parent);
if (deferSetEditable != null && getSourceViewer() != null) {
getSourceViewer.setEditable(deferSetEditable.booleanValue()) ;
deferSetEditable = null;
}
}
