There are a copule of common reasons for that:
1. The layer in the map is not referencing the temporary featuresource,
but the permanent
2. The layer is not visible in the map
3. The layer is out of scale range
4. The layer is below another visible layer
My guess is that you have hit #1.
When you create the temporary resource, you must also create a copy of
the layer,
and update the layers featuresource to point at the temporary featuresource.
So, steps are:
1. Get layerdefinition
2. Update the resourceid of the featuresource to match the temporary
featuresource
3. Save the updated layer definition
4. Change the runtime map to use the newly created temporary layer resource.
Hope that helps.

Hi all, first post and new time user to Mapguide, so go gently please!
Basically, my goal is to digitize a polygon and once complete I want to
display the digitized polygon on the map. The problem being this needs to be
on a per user, per polygon basis. (In other words, each user using the
system should only see their polygon they have just created).
My thought to complete this task was to create a temporary layer and add the
polygon to that layer. The code I have used originated from a MapGuide
course that I went on. The problem is that the code appears to work in that
there are no exceptions thrown, but the polygon is not displayed on the map.
If I change the code so that the polygon is added to a permanent layer the
polygon is added and displayed correctly.
What am I doing wrong?
(I can add my code if people need to see what I'm doing)
(Software I'm using is MapGuide open source ver. 1.2, and visual studio 2005
and C#/.NET platform version 2.0)
