It needs the reference to get the connection object, which is used to
retrieve the<br>
layerdefinition and the name of the primary key column (the property
"IDs").<br>
<br>
There is also an overload that takes the runtime map instance.<br>
<br>
Feel free to write an overload that constructs the RuntimeMapLayer with
just a connection object instead.<br>
If you attach a patch to a ticket, I will put it in trunk.<br>
<br>
The runtime layer stuff is a bit clumsy, if you have ideas for
improvements, I'm all ears.<br>
<br>
Although that exception should not be able terminate the MgServer
service...<br>

<pre wrap="">OK, initializing the RuntimeMapLayer works but after saving back the modified
map to the Session-Repository the MgServer service is terminated. I have to
restart the service and also the IIS.
When I debug my application I relize an error on the
RuntimeMapLayer.IDs-property:
'runMapLayer.IDs' threw an exception of type 'System.Exception'
Message: Cannot reload ID's because the layers parent is not set
StackTrace: at
OSGeo.MapGuide.MaestroAPI.RuntimeClasses.RuntimeMapLayer.FindResourceIDs()
at
OSGeo.MapGuide.MaestroAPI.RuntimeClasses.RuntimeMapLayer.get_IDs()"
So I've looked at the parent-property of the RuntimeMapLayer and it is set
to "null". Does this cause the problem? The parent-property is of type
MapDefinition and I'm wondering why I need a reference to the MapDefinition
at all?
What ist the best practice, when I want to add a new layer at runtime from
an exisiting MapDefinition in Library-Repository and which methode should I
use

You need to change line 1545 of the file
MaestroAPI/Generated/LayerDefinition-1.3.0.cs
<a class="moz-txt-link-freetext" href="http://trac.osgeo.org/mapguide/browser/trunk/Tools/Maestro/MaestroAPI/Generated/LayerDefinition-1.2.0.cs#L1545">http://trac.osgeo.org/mapguide/browser/trunk/Tools/Maestro/MaestroAPI/Generated/LayerDefinition-1.2.0.cs#L1545</a>
Before:
public static readonly string SchemaName = "LayerDefinition-1.2.0.xsd";
After:
public static readonly string SchemaName = "LayerDefinition-1.3.0.xsd";
I will put that fix in trunk, but for now you can use it if you compile
yourself.
This also means that you cannot save 1.3.0 layers from Maestro.

<pre wrap="">Hi,
I'm trying to add a layer to the runtimemap using the MaestroAPI:
MapLayerType layer = layerArray[layerName];
RuntimeMapLayer runMapLayer = new RuntimeMapLayer(layer);
runMap.Layers.Add(runMapLayer);
On creating the RuntimeMapLayer I get the following Error:
error in XML document (2,117)
I suppose it's the same error like in this
<a class="moz-txt-link-freetext" href="http://n2.nabble.com/Can%27t-open-LayerDefinition-with-maestro-tt3276282.html#a3276282">http://n2.nabble.com/Can%27t-open-LayerDefinition-with-maestro-tt3276282.html#a3276282</a>
thread and therefore I build the MaestroAPI.dll
from trunk as mentioned there. But the error still remains.
Any idea?
Thanks, Gunter
