[mapguide-users] Fusion - Session ID invalid because the session separator character was not found

[Chris Claydon]

The ease of porting scripts from the basic viewer to the fusion viewer can vary substantially depending on what your code does. The underlying web tier API is the same, but the viewer APIs are different. In most cases there are equivalent functions in Fusion, the tricky part is figuring out what they are because the documentation is sparse. There are several people on this mailing list that have experience in porting scripts, and they are probably the best resource for solving any problems you run into.

For the issue of determining the session ID, are you able to capture the request that is being made to your script using Fiddler? The session parameter may be missing, but my suspicion (from looking at the code for the InvokeUrl Fusion widget) is that it is just getting sent in uppercase - so maybe try changing "session" to "SESSION" before digging deeper with Fiddler.

Chris.

Subject: [mapguide-users] Fusion - Session ID invalid because the session separator character was not found

Hi List.
I'm modifying the Ajax utility demo found here http://enterprise.mapguide.com/utilitymap/ .  I made all my modifications and had my shiny new application up and running in a basic AJAX layout.
I'm now trying to move it across to a Fusion layout.  All code works fine in the basic web layout, but in the Fusion layout I get the error below.  So I guess the question is how does Fusion differ from Ajax when it comes to passing through a session ID?  Any code out there that shows how this is done in fusion?
Further to this, if I get across this initial hurdle, are there a pile more waiting for me by taking something created for AJAX and cramming it into Fusion?
Thanks for your help.
Fraser
