I think I'm having problems with changing existing dynamic layer's Filter
property (the one that filters data from FeatureSource) using .NET. Here's
the approach that doesn't report any error, but when I refresh the map there
are no changes to the layer - new filter doesn't get applied.

When the MapDefinition is turned into a runtime Map, it copies
properties from the layerdefinition.
This means that you will see no changes, even if you choose to modify
the LayerDefinition.
You must modify the layer copy in the runtime map.
Fortunately, that is actually easier than what you
This layer removal thingy is funny. Could anyone, plese, explain what's going

=== This works:
Dim layerName as String = TestLayer
Dim map As MgMap = ...get active MgMap from session...
Dim layerCol As MgLayerCollection = map.GetLayers()
Dim layerToRemove As MgLayer = Nothing

properties, though, but not Filter property (and I have no clue why's that,
probably somebody forgot to expose it).
So I guess I still
