<p class=MsoNormal><span style='color:#1F497D'>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.<o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>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.<o:p></o:p></span></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Hi
List.<o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I’m
modifying the Ajax utility demo found here <a
href="http://enterprise.mapguide.com/utilitymap/">http://enterprise.mapguide.com/utilitymap/</a>
. I made all my modifications and had my shiny new application up and
running in a basic AJAX layout. <o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>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? <o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>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?<o:p></o:p></p>
<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Thanks
for your help.<o:p></o:p></p>
