#203 How to use contexts?

[Nikolaj Weise]

I have defined a WorkflowContext in device.xml:

<WorkflowContext Handle="myWorkflowContext">
  <Type>
    <CodeId>MDCX_MY_WORKFLOW_CONTEXT</CodeId>
  </Type>
</WorkflowContext>

Now I'm trying to use it on client side (pseudo code):

mdsContexts = bicepsClient.getMDSContexts
contextElements = mdsContexts.getMDSContextElements
find DefaultBICEPSWorkflowContext in contextElements:
  workflowContext.getContextElementItem // returns null

getContextElementItem returns null because in BICEPSProxyUtil.getCurrentStateFromDevice(...) it tries to determine the state's class. "myWorkflowContext" is of class ContextAssociationState. That's really weird because I'm using this method on a WorkflowContext with handle "myWorkflowContext".

I do not understand the relationship between Contexts (WorkflowContext, PatientContext, ...) and ContextAssociationState.

How to access a context's content from client side?
