Bug 139063 [Field Assist] - API - behavior of text insert not taking selection into account
Field Assist Example - set acceptance style to "Insert into field content" - type some text into the text and combo - select a subset of the text and invoke content assist - choose a proposal in the popup outcome: text is inserted at the insertion point expected: text should be inserted, but should replace any selected text Is this a regression?

for (int i = 0; i < items.length; i++) {

						IContentProposal proposal = newProposals[i];
						item.setText(getString(proposal));
						item.setImage(getImage(proposal));
						item.setData(proposal);
					}
					proposalTable.setRedraw(true);

				if (newProposals.length > 0) {
					selectProposal(0);
				} else {
					
					if (infoPopup != null) {
						infoPopup.close();
					}
