[mapguide-users] prob with GetSelectionXml()

[Kenneth Skovhede, GEOGRAF A/S]

Its the runtime layer's ID, which is a guid string, and changes for each 
invocation of the map.
(eg, you can't save it and use it in another session).

Selection xml looks like this:

<Layer id="layer guid">
  <Class id="feature class">
     <ID>base64 encoded primary key value</ID>
   </Class>
</Layer>

You can have multiple <Layer> tags, multiple <Class> tags, and multiple 
<ID> tags.

> hi all! did you know what does" id" in <layer id=255.....> returned by selection xml mean? cause when i got the XmlSelection from map and i use it for getting layers it contains i've error wich say that layers is nothing but the selection is nt i've verifyed it the selection i got from map is not empty but the layers are nothing, so i think that can be caused by the "id" in <layer id=255.....> returned by the selection if that mean the session for example cause me when i create layer i do it with "library://......mapdefinition" and not "Session//....mapdefinition" so i think that if the id on <layer id=255.....> means the session used by user i think that layer contained on selection won't be known, but i'm not sure please if you have some idea tell it me, thanks a lot on advance.
