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.

		private IContentProposal getSelectedProposal() {

					return null;
				}
				return proposals[i];
			}
			return null;
		}
		/*
		 * Select the proposal at the given index.

		private void selectProposal(int index) {

					.isTrue(index >= 0,
							"Proposal index should never be negative"); 
			if (!isValid() || proposals == null || index >= proposals.length) {
				return;
			}
			proposalTable.setSelection(index);
			proposalTable.showSelection();
			showProposalDescription();
