I set this property in my Properties.dev: log4j.logger.er.extensions.ERXApplication.RequestHandling=DEBUG and then I looked at all the uri's of the requests coming in. They have /ajax/ in there and when the dialog first comes up I see a few /_wr_/ and I guess the browser caches those since I don't see requests for those anymore on subsequent requests after the dialog is displayed. All the requests for the "many clicks" I mentioned have /ajax/ in them. I don't see any /wo/ requests mixed in. Also I set a breakpoint in ERXAjaxSession.java at the only place it calls super.savePage() where I assume the current page would be saved but I never hit the breakpoint. I would think that regular component requests would be generating new context IDs and therefore saving the page in the cache for those context IDs. But I don't see the page getting saved. :-/ > >>>> The dialog has a closeUpdateContainerID bound with the id of an ajax >>>> update container to refresh, which it does refresh upon closing the >>>> dialog.

It sounds like a /wo/ URL so that suggests to me that something in your > dialog is generating /wo/ or /wa/ requests that are pushing the page out of > the standard page cache. I did not see any /wo/ nor /wa/ requests. They are all /ajax/ requests. Maybe I'll try to create a test Wonder app with an ajax modal dialog with a single ajax link in it that displays the current time when clicked... Then I can click it many many times. Then close the dialog and then click on a link on the page afterwards to see if I can reproduce. > Chuck > > -- > Chuck Hill Senior Consultant / VP Development > > Come to WOWODC this July for unparalleled WO learning opportunities and real > peer to peer problem solving!
