Subject: _expression_ Evaluation in DSF/TCF

Hi,

I have been working on a module that interacts with the Eclipse debugger programmatically.

So far I have been able to perform all the required actions I have needed without having to invoke any implementation specific code, and this has worked with the CDT/DSF/TCF debugger.

However, I am now attempting to access expressions vie the IExpressionsManager interface and this seems to be problematic with the TCF debugger.

While I am able to add IExpression objects to the "expressions" view via the IExpressionsManager, and the values in the view are displayed properly, The IExpression object I have has a null value and context.

I found the following code in TCFNodeExpression.Java which seems to attempt to deal with this, however after observing execution, it seems that Object returned by the getDebugContext() method is a TCFNodeExecContext, which does not implement IDebugElement or ILaunch, and as such the IExpression context remains null.



Is there some other way for me to get an _expression_'s value without having to specifically invoke a TCFTask?


Thanks
