[news.eclipse.webtools] Re: faceted project events

[Konstantin Komissarchik <kosta@xxxxxxx>]

Hi Brian,

The fact that you are seeing a PROJECT_MODIFIED event on close/open is 
actually a bug, which has been fixed in the 2.0.x and newer code lines.

There is an open enhancement request to provide a PROJECT_INITIALIZED 
event that would cover opened/imported cases.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=198165

I haven't thought about providing events to cover the closed/deleted 
case, but it may make sense to do. Please add your thoughts on this to 
the above enhancement request. Note that PROJECT_INITIALIZED event will 
not _exactly_ represent the open/import case. The reason is that the 
event will only be generated when some code requests IFacetedProject 
metadata for that project. We don't pro-actively scan for new projects 
and initialize them for performance reasons. This distinction may not 
matter for your situations, though.

Note that the general answer is that the faceted project events are not 
meant to replace the facilities provided by the platform's resource 
change listeners. Your co-worker Paul Fullbright and I had a discussion 
on this scenario some months ago. He should be able to share with your 
some code that uses the resource change listeners to handle this 
scenario in the meantime.

Let me know if you have further questions.
