Perhaps you could post your code so we can take a look?

I know the map is visible on the map (Well, at least it was set to
visible

map, as it
shows up in the TOC list on the left of the map. I have also tried
turning
all the other layers off (making them invisible) to see if it were
the issue
of them being below other layers, and the polygons still didn't
show up.
So, I guess that the issue is either 1. or 3.

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)
