[mapguide-users] Scribble markup application question

Tue Apr 7 13:05:59 EDT 2009

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

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.

Warren M
