Working on fix. Created attachment 170690 [details]
Fix Patch - New Class
The issue here stems from my gross misunderstanding of context assist back when I wrote the paged content assist. Luckily the fix is not horrible.
Part of the issue is that the context assist is not paged but the StructuredContetnAssistProcessor was attempting to look up paging information to decide whether to display legacy extension contributions (that was the cause of the NPE). Once the NPE was fixed there were some issues with implementations ofIContentAssistProcessor#getContextInformationValidator as well as ICompletionProposalComputer#computeContextInformation.
I actually have two slightly different fixes for this. The first one I am attatching with this comment creates a new class org.eclipse.wst.sse.ui.internal.contentassist.ContextInformationValidator that pulls the IContextInformationValidator implementation out of AttributeContextInformationPresenter so it can be accessible by StructuredContentAssistProcessor#getContextInformationValidator so that #getContextInformationValidator can return this new ContextInformationValidator rather then null. In this patch AttributeContextInformationPresenter is then updated to extend from the new ContextInformationValidator.
But since this is going in to need to go in WTP 3.2 I thought it may not be possible to introduce a new class so I will attach another patch that does not have this class. The only real difference between the two patches (other then better readability) is that without the new class StructuredContentAssistProcessor#getContextInformationValidator will return null.
In both patches HTMLStructuredContentAssistProcessor, JSPStructuredContentAssistProcessor, and XMLStructuredContentAssistProcessor override #getContextInformationValidator to return an instance of AttributeContextInformationPresenter because of its its presenter interface implementation.
The other issue is that instead of seeing the context information as soon as ctrl+shift+space is invoked a content assist list with two options looking (and reality) identical options are displayed, clicking or pressing enter on either results in the same context information being shown. This is caused by org.eclipse.jst.jsf.facelet.ui.internal.contentassist.XHTMLContentAssistProcessor a legacy content assist extension that is providing the same context information as StructuredContentAssistProcessor. I will be opening a bug on the owner of this extension to rectify this issue.

It turns out this duplication was actually caused by the fact that XHTMLContentAssistProcessor extends AbstractContentAssistProcessor which was providing the duplicate context information. Because AbstractContentAssistProcessor has been depreciated and the only people still using it would be extending content assist through the legacy method this provided context would always be duplicated by the context provided by the new framework. Thus I have updated the patch to make it so that AbstractContentAssistProcessor returns an empty array preventing any duplication. * Explain why you believe this is a stop-ship defect. Or, if it is a "hotbug" (requested by an adopter) please document it as such. Context information is made completely unavailable in SSE editors. Fixing just the NPE alone, however, causes it to return invalid information--a clear regression from 3.1. * Is there a work-around? If so, why do you believe the work-around is insufficient? None. * How has the fix been tested? Is there a test case attached to the bugzilla record? Has a JUnit Test been added? Manually tested. No prior unit tests exist to establish the regression. * Give a brief technical overview. Who has reviewed this fix? Avoids the NPE ad re-adds the context information that was missing before. The old base content assist processor class is also changed not to return any context information to avoid conflicts from legacy contributions that extend our older code without specifically implementing that support. Code reviewed and also tested by me. * What is the risk associated with this fix? Medium. I can't pretend this is a small change, but most of it is refitting the old functionality into the new proposal-computer framework. I would like to see this fixed, since such a large regression (and source editing such a central function). Should be well tested by JSF (and Dali?) teams too ... make sure there's no special cases. Approving based on major loss of function and this being a regression. serious regression. Released v201006030742. (In reply to comment #15) > Released v201006030742.
