Can't get hold of the user.waveset.roles in my workflow

Question

Hey,
I am developing a workflow process that adds a role to each user during reconsiliation if they don't already have it.
1. It gets the user view.
2.. It checks to see if the user has a particular role. (This is where my problem lies, as the user.wavset.roles value returns null).
3. If the user already has the role the process ends.
4. If the user doesnt have the role it appends it to user.waveset.roles and then checks in the user view.
So at the moment the process always thinks the user hasnt got the role because I can't get user.wavset.roles to return a value. Although I can access it when I append!?
Any ideas anyone why I cant access the user.waveset.roles value in the second step? It prints out that the value is null on the stack trace.
The Activity code looks like this:
<Activity id='5' name='Check Roles'>
<Transition to='end'>
<match>
<upcase>
<block trace='true'>
<ref>user.waveset.roles</ref>
</block>
</upcase>
<upcase>
<rule name='Entrust GetAccess Role Name'/>
</upcase>
</match>
</Transition>
<Transition to='ProcessUser'/>
<WorkflowEditor x='163' y='9'/>
</Activity>

Check once if the variable "user" is holding the user view or not.
I'm not sure if you have already tried this....
If we are getting the user view using a workflow service then by default the fetched user view is placed in a variable called "view". So we may have to use 'view.waveset.roles'.
If we want to store the fetched user view in the variable "user", then in the Action that gets the user view, we may have to return the value from "view" to "user", wherein "user" is a global variable defined at the workflow level.Then we can refer "user" in all the activities throughout the workflow.
