Hi!Chuck is right, your completely screwing WebObjects up. pageWithName returns you a component initialized for a given context (WOContext, not EOEditingContext). If you are using the same pages for different situations and mixing up sessions and stuff, NOTHING will work. Nothing. Even if it APPEARS to work on your computer, it won't on production with many users using the app simultaneously. I can't even think about how many problems will it create, WO is simply not supposed to work like that.
Also, WebObjects already caches a lot of stuff internally (if you compare the time it takes to load a page generated by a given component the first and subsequent times, you'll see this clearly), so you don't need to hack in any more caches, you're probably making the performance worse instead of improving it (and killing correctness, of course).
Delete all that, and simply use pageWithName normally. Yours Miguel Arroz On 2009/10/13, at 20:24, Chuck Hill wrote:
You are messing up WO's maintenance of page state. I am surprised this does not cause more issues for you.Why are you doing this? It seems like a rather bad idea.

Everytime the "pageWithName" method is called, thedictionary is queried in order to determine if the requested page does already exist, if true the existing page is returned, else a new one is generated and stored in the dictionary. This is made in Application.javaby overriding the "pageWithName" method: public WOComponent pageWithName(String aName, WOContext aContext) { Object result = null; if ( aContext.hasSession() ) result =((NSMutableDictionary) ((Session)aContext.session()).cachedPages()).objectForKey(aName);if ( result == null ) { result = super.pageWithName(aName, aContext); if ( aContext.hasSession() ) if ( aName != null )((NSMutableDictionary) ((Session)aContext.session()).cachedPages()).setObjectForKey(result,aName); } return (WOComponent)result; }This works with one exception. Making changes on Enterprise Objects isnot possible in every case. Saving changes works, if always the sameobject is changed but not if two different objects are changed (changing the first, saving the changes, then changing the second and saving the changes). But if making changes on a object, saving it, and then revertthe changes (to the same state as before changing it the first time), making changes on other objects is possible. As mentioned in the WO API Reference, for pages being stored in a variable the "ensureAwakeInContext" method has to be called, but this has no effect. Same if refreshing the objects in the default editingcontext ("refreshAllObjects", "refaultAllObjects") which is used on allpages. Any suggestions or other hints would be appreciated.
