Bug 293199 [FieldAssist] Content assist popup appears in the wrong location (bounds are incorrect)
When content assist is attached to a Text widget, the location of the suggestion popup is incorrect. Content assist is applied as follows: bc. TextContentAdapter textContentAdapter = new TextContentAdapter(); IContentProposalProvider provider = // provider ContentAssistCommandAdapter adapter = new ContentAssistCommandAdapter(nameText, textContentAdapter, provider, org.eclipse.ui.fieldassist.ContentAssistCommandAdapter.CONTENT_PROPOSAL_COMMAND, new char[0],true); adapter.setProposalAcceptanceStyle(ContentAssistCommandAdapter.PROPOSAL_REPLACE); I'm not sure if it matters, the Text is embedded in an expandable section in a SashForm in a multipage editor. attaching two screenshots showing popup placement issue.

if (isValid()) {
			
			watchModify = false;
			controlContentAdapter.setControlContents(control, text,
					cursorPosition);
		}
	}
	/*
	 * Insert the specified text into the control content, setting the
	 * cursorPosition at the desired location within the new contents.
	 */
	private void insertControlContent(String text, int cursorPosition) {
		if (isValid()) {
			
			watchModify = false;
			
			
			
			
			
			if (controlContentAdapter instanceof IControlContentAdapter2
					&& selectionRange.x != -1) {
				((IControlContentAdapter2) controlContentAdapter).setSelection(
						control, selectionRange);
			} else if (insertionPos != -1) {
				controlContentAdapter.setCursorPosition(control, insertionPos);
			}
			controlContentAdapter.insertControlContents(control, text,
					cursorPosition);
		}
