XEclipse Offline

Hi all, I have a few doubts that might arise when we're implementing off-line operation of XEclipse. 1. Currently, when the user saves a page after editing, no checks are made to ensure that if the same page has been modified by someone else at the same time. But avoiding this is a problem since that would require us to retrieve the page again (to check locks) every-time user tries to save a page. 2. Also, when a page is retrieved for the first time if there are any locks are present, we must convey that information to the user (in the extreme case, we can disallow any attempts to modify a page with any locks in it). 3. How permissions should be conveyed to users ? And how to handle them ? (currently, this is ignored) We can use different icons for all of these situations (for permissions , dirty pages etc.), but that would require a lot of icons (and we're running out of appropriate icons too). Any thoughts ? Thanks. - Asiri
