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?

* @param autoActivated
	 *            a boolean indicating whether the popup was autoactivated. If
	 *            false, a beep will sound when no proposals can be shown.
