Bug 183650 [FieldAssist] ContentProposalAdapter with Text produces unwanted popup on Enter
Build ID: I20070323-1616 Steps To Reproduce: 1. Setup a ContentProposalAdapter (using ContentProposalAdapter.PROPOSAL_REPLACE) with some proposals on a Text control. 2. Type some valid text into the Text control 3. Hit "Enter" (or select from the dropdown) More information: ContentProposalAdapter has a private controlListener that calls autoActivate() on a SWT.Modify event. This is fine except it gets triggered from ContentProposalAdapter.proposalAccepted(). The result is that you select one of the items and it modifies the Text control causing the popup to display again, which goes around until the user hits ESC to make it go away.

* Construct a content proposal adapter that can assist the user with
	 * choosing content for the field.
	 * 
	 * @param control
	 *            the control for which the adapter is providing content assist.
	 *            May not be <code>null</code>.
	 * @param controlContentAdapter
	 *            the <code>IControlContentAdapter</code> used to obtain and
	 *            update the control's contents as proposals are accepted. May
	 *            not be <code>null</code>.
	 * @param proposalProvider
	 *            the <code>IContentProposalProvider</code> used to obtain
	 *            content proposals for this control, or <code>null</code> if
	 *            no content proposal is available.
	 * @param keyStroke
	 *            the keystroke that will invoke the content proposal popup. If
	 *            this value is <code>null</code>, then proposals will be
	 *            activated automatically when any of the auto activation
	 *            characters are typed.
	 * @param autoActivationCharacters
	 *            An array of characters that trigger auto-activation of content
	 *            proposal. If specified, these characters will trigger
	 *            auto-activation of the proposal popup, regardless of whether
	 *            an explicit invocation keyStroke was specified. If this
	 *            parameter is <code>null</code>, then only a specified
	 *            keyStroke will invoke content proposal. If this parameter is
	 *            <code>null</code> and the keyStroke parameter is
	 *            <code>null</code>, then all alphanumeric characters will
	 *            auto-activate content proposal.
