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.

proposalTable.setHeaderVisible(false);
			proposalTable.addSelectionListener(new SelectionListener() {
				public void widgetSelected(SelectionEvent e) {
					
					
					if (e.item == null) {
						if (infoPopup != null) {
							infoPopup.close();
						}
					} else {
						showProposalDescription();
					}
				}
				
				public void widgetDefaultSelected(SelectionEvent e) {
					acceptCurrentProposal();
				}
			});
			return proposalTable;
