If you want to add it before the map loads, there is no session.
This happens because the MapGuide AJAX viewer creates the session and
the runtime map.
You have to create the LayerDefinition and the MapDefinition in the
Library repository.
My best solution for this is to create a folder like "Libray://Temp".
Then create a GUID for each resource, and dump it here.
After the AJAX viewer loads, you may delete the created items, as it
then uses the RuntimeMap in the session repository.

Its just a copy of the parcelmarker.xml from the samples. It works otherwise
with tasks, but I couldn't seem to get it work before the map is loaded.

What does the feature source xml look like? It seems that feature source

Hi all,
I am trying to add a dynamic layer to a map but before loading the map in
the map frame. It is supposed to work on some query string parameters and
should add a dynamic layer based on that information. I can add the Map
to the session. I want to query the map from the Session Repository and
work on a copy, however I keep getting the
Session:xxxx//PointPlotter.FeatureSource Exception occurred in method
MgResourceDefinitionManager.GetDocument at line 476 in file
c:\build_bond_area\mapguide_open_source_v1.2\build_18.1\mgdev\server\src\services\resource\ResourceDefinitionManager.cpp
error.
Here is how I constructed the logic:
1- Make a new MgSite object
2- Use MgSite->Open with a new MgUserInformation object
3- store the session ID in a variable
4- Check GET parameters
5- if records exists depending on the GET parameters, make a new
MgSiteConnection object
6- Open this MgSiteConnection object with the session ID
7- Create a ResourceService by using MgSiteConnection->CreateService
8- Open the map by using $map->Open($resourceService, 'MapName') (EDIT: I
used the $map->Create() function)
9- Verify and add layers (building upon the Sheboygan Find Parcel example
from MG 1.1 samples)
Do I need to explicity add a feature source to the session repository?
But I think that's what exactly the CreatePointPlotterFeatureSource
function does from the findparcelsfunctions.php does in the samples.
And this error occurs when I call the CreatePointPlotterFeatureSource
function. When I add a new FeatureSource in the form of
MgResourceIdentifier it works fine (i.e. no errors generated), but on the
first call to the above-mentioned function it crashes. Apparently it
doesn't execute even the first line which I changed into an "echo" for
debugging purposes.
Anybody got any tips?

uXuf
