[mapguide-users] Working with the current selection

[Alain Lebatard]

Brian,

Are you opening your map with the DWF or the AJAX viewer?

The selection object exists on the server-side only for the AJAX viewer.
The DWF viewer does not need that object as it maintains the selection
internally on the client-side. 

When you open a web layout with the AJAX viewer, both map and selection
objects are created at the same time, and they both co-exist for the
lifetime of the session. However if you opened the web layout with the
DWF viewer only the map object exists, which would explain the error you
are seeing.

Alain

Yes, thanks for the response. But if that was the case it would not get
by the line above it that says:

map.Open(resourceService, "myMap")

Additional error detail

Exception occurred in method MgResourceDefinitionManager.GetDocument at
line 856 in file
c:\build_tux_area\mgdev\server\src\services\resource\ResourceDefinitionM

Are you sure that myMap is a valid name for a map in your repository?
It
should also be the name of the map you are working with when this code
is
executed.

Has anyone been able to work with the active selection in a map?  (I am
working with the sample in the development guide (Page 39-40)

I keep getting an error saying:  

Message	"Resource was not found:
Session:72234676-0000-1000-8004-00142260e7d1_en//myMap.Selection"
String

I am able to open the map and the session is valid.  I am basically
copying
the code (although I am converting to asp.net..)

Here is some of the code:

Dim mgSessionId As String = GetParameters()("SESSION") Dim matches As
Integer = 0  ' Variable to control output results.
Dim mapUpdated As Boolean = False
MapGuideApi.InitializeSockets()
InitializeWebTier()

Dim userInfo As MgUserInformation = New MgUserInformation(mgSessionId)
Dim
siteConnection As MgSiteConnection = New MgSiteConnection
siteConnection.Open(userInfo)
Dim resourceService As MgResourceService =
siteConnection.CreateService(MgServiceType.ResourceService)
Dim featureService As MgFeatureService =
siteConnection.CreateService(MgServiceType.FeatureService)
Dim queryOptions As New MgFeatureQueryOptions Dim map As New MgMap
map.Open(resourceService, "myMap") Dim Selection As New MgSelection(map)

ERROR OCCURS at the line below
Selection.Open(resourceService, "myMap")

Thanks for any suggestions
