You can start to override this API and just log, to understand how WebObjects works with pages and contextIDs. HTH, Stephane Le 13 oct. 09 à 10:29, Andri vonAllmen a écrit :Dear List,in an Applications Session, a NSMutableDictionary object is used for "caching" pages. 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.java by 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 revert the 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 thishas no effect. Same if refreshing the objects in the default editing context ("refreshAllObjects", "refaultAllObjects") which is used onall pages. Any suggestions or other hints would be appreciated.
