[mapguide-users] ajax viewer with MG 4

[Greg Neff]

Thanks for the response.



This is just on my local machine so it’s not available for you to try the
url but here is how the layout is embedded in the page.



<frameset id="master" rows="30,*" frameborder="no" framespacing="0">

    <frame name="titleFrame" id="titleFrame" frameborder="0"
marginwidth="0" marginheight="0" scrolling="no" src="title.html">

   <frame name="viewerFrame" id="viewerFrame" frameborder="0"
marginwidth="0" marginheight="0" scrolling="no"

        src="../mapviewernet/ajaxviewer.aspx?SESSION='<%=sessionId
%>'&WEBLAYOUT='<%=webLayout
%>'&Username=<%=defaultUser%>&Password=<%=defaultPassword%>">

</frameset>



A frame before the layout loads and then the error.  Here is how the page
looks:

Can you share the direct Layout URL and the URL you are embedding?

and trying to get an old layout with the ajax viewer working.  It’s still
working on a different server with Mapguide 3.1.2.9484.



I have updated my map definition and web layout to the latest resource
versions.



I can preview the layout just fine in Maestro but when I try to load it
into a frame on a web page I get the following error:



Invalid repository type. Bad Resource Identifier: -
CSharp_OSGeofMapGuide_new_MgResourceIdentifier___() line 11524 file
C:\Workspace\mg-4.0\MgDev\Bindings\src\Bindings\DotNet\PlatformBase\PlatformBaseUnmanagedApi_wrap.cpp
- MgResourceIdentifier.ParseIdentifier() line 457 file
C:\Workspace\mg-4.0\MgDev\Common\PlatformBase\Services\ResourceIdentifier.cpp



Does anyone know why I might be getting this error.
