Hi all,
I have asked this question couple of times before but the slution doesn't
get me my result.
I am getting a NULL value from the following line of code when the method
is called after the creation of the editor

public void setMyBoolean(boolean editable)
{
ISourceViewer viewer = getSourceViewer();
viewer.setEditable(editable); //there is no outcome from this line of
code
}

Then I found out a hack for this from Andrew that does get me the object
but still doesn't get seteditable(false) to work instead if i call
viewer.gettextWidget.setEnabled(false); then the editor area is made
readonly but I can't get anything copied from there or entered in the
editor through other programs.

if (part instanceof CompilationUnitEditor) {
CompilationUnitEditor editor = (CompilationUnitEditor)part;
ITextViewer viewer =
(ITextViewer)editor.getAdapter(ITextOperationTarget.class);
}
I ahve found nothing substantial about this getSourceViewer() in the
archives but there are too many question asked there,that shows other
users had some difficulty in getting hold of it.
i would really appreciate if I can know of any toehr way of getting hold
of the sourceViewer of the active editor.

I would really apprecaite any pointers.
