When building a chameleon template using a service in stance the following issue
occurred:

1 added a mapdhtml widget. context map is displayed
2 add zoomin widget. when the zoomin tag is defined with the sub tag <image/>
(see below). when the user tries to zoom the app fails.

The three tag structure below one of them only works when the Textbutton shared
resource is defined.


Tag Structure 1:
---------------
if the zoomin widget is defined as:

<cwc2 type="ZoomIn" visible="true" image="buttons/button_zoomin_1.png"
imagewidth="24" imageheight="24" imagetip="Zoom In" toolset="Navigation"
default="true"/>

Tag Structure 2:
---------------
if the images are defined for different states with no "state" sub tag attribute
the application works, but the button image is always based on the last <image/>
sub tag defined, in this case it always shows the pushed in "selected" button. 


<cwc2 type="ZoomIn" visible="true" imagewidth="24" imageheight="24"
imagetip="Zoom In" toolset="Navigation" default="true">
   <image image="buttons/button_zoomin_1.png"/>
   <image image="buttons/button_zoomin_2.png"/>
   <image image="buttons/button_zoomin_3.png"/>
</cwc2>

Tag structure 3: 
----------------
No shared resource but the state sub tag attribute is defined. This creates the
failure because in the template there is no default "Textbutton" shared resource.

<cwc2 type="ZoomIn" visible="true" imagewidth="24" imageheight="24"
imagetip="Zoom In" toolset="Navigation" default="true">
  <image state="normal" image="buttons/button_zoomin_1.png"/>
  <image state="hover" image="buttons/button_zoomin_2.png"/>
  <image state="selected" image="buttons/button_zoomin_3.png"/>
</cwc2>

In both Tag structure 2 and 3 there should be some error captured for the
application developer stating the dependency of the <image/> sub tag to contain
button states, which results in the dependency for the "Textbutton" shared
resource to be defined.

Last comment: Ideally you should be able to set the state of an image without
using the shared resource.
