Adding a fused cached ArcGIS layer to the white list filter by its ID causes a NullPointerException in building client.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create an ArcGIS source with a fused cached layer made up from many 
sub-layers. 
2. Using the data source Black/White layer filter remove all layers then add 
the cached layer based on the layer ID listed in the Client.
For example:
-*
+ts-env_basemaps/national_basemap/
3. Now try to rebuild the client. It will give an undefined error.
4. Changing the white list to use a wild card fixes the problem, and reports 
that there are 88 layers (even though there is really only 1).
+ts-env_basemaps/national_basemap*

What is the expected output? What do you see instead?
Cached layers are fused by many sub-layers that are not individually available. 
As a result it should be treated as a layer. Therefore its layer ID should 
represented in the white list.

Work around:
Use a wildcard to pick up all the sub-layers. These will be fused (logically) 
into one layer in the client.

What version of the product are you using? On what operating system?
1.4.6, Linux server

A slight variant of this problem occurs when adding children layers using the 
following pattern:
+ts-env_pmst/pmst_named_regions/*
It fails but adding a specific child is OK such as 
ts-env_pmst/pmst_named_regions/2_NRMPROG_SDE.nrm_regions but you don't get the 
parent directory, and using the following is OK:
+ts-env_pmst/pmst_named_regions*
