Hi!
In one of our refactorings (extract method), we'd like to give the user the
ability to modify the selected code in the dialog of the refactoring. It
would be nice if this selection widget had the same appearance as the other
editor windows, or like the formatting-preferences page. I came up with this
code:
Map<String, String> map = new HashMap<String, String>();
selectionPreview = new RubyScriptPreview(map,
modifySelectionEditorComposite);
FormData textLData = new FormData(0, 0);
textLData.right = new FormAttachment(1000, 1000, -80);
textLData.left = new FormAttachment(0, 1000, 0);
textLData.top = new FormAttachment(0, 1000, 0);
textLData.bottom = new FormAttachment(1000, 1000, 0);
selectionPreview.getControl().setLayoutData(textLData);
selectionPreview.setPreviewText("class Test\ndef
test\nend\nend");
And it works so far, but I get this exception when the widget is used:
Exception in thread "org.rubypeople.rdt.internal.ui.text.RubyReconciler"
java.lang.NullPointerException

What is the right way to use this widget? Or am I using the wrong one?
Regards
Mirko
