Warren,
It has been some time since I wrote Scribble and my head is currently into OBJECTARX/Oracle but I believe its purpose is to stuff the currentscribbleselectionXMLcntrl.value for the dark-side. As to why, well I just did it that way. Yes, that is exactly what it does. As for the error it looks to me that I store the original but on exit I never put it back. Since I did not do it, check out the <body> "onunload" event. I would think you just have to put the original back. mainFrame.OnSelectionChanged = originalOnSelectionChanged; r, dennis ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Warren Medernach Sent: Tuesday, April 07, 2009 11:57 AM To: MapGuide Users Mail List Subject: [mapguide-users] Scribble markup application question I'd like to know if somebody that knows the Scribble app can explain why the app implements a local selection changed handler and what the purpose of it is: LocalOnSelectionChangedHandler >From what I can see, it just sets the selectionXML to one of the hidden fields, is this correct? I've created a wrapper of sorts for the Scribble app that takes part of the GT markup app for managing the creation and loading of 'local' and global' markup resources based on a user login, and then the scribble app for the feature creation. The app works great creating and deleting features. However, when I exit the editing mode and close the resources, the app goes back to the default Task Page. At this point, if I try to select objects on the map, a JScript runtime error is thrown: "Can't execute code from a freed script" and the app stops on a parent.OnSelectionChanged(); call in the mapframe.aspx. I may be off-track on this error, but I think it has something to do with the local onchanged handler in the Scribble app? Any insight or comments would be greatly appreciated, thanks so much.
