Hi,

I'm just get started with the MDT-OCL, and follow the guidance from here:
http://sdqweb.ipd.uka.de/wiki/Evaluate_OCL_Constraints_for_M odel_Instances

but problem comes out when I press 'interactive ocl' in the console, the error box says:
------------------------------------------
'show console view' encountered a problem
error
detail: error
------------------------------------------

is there anybody know the reason?

Thank you very much for the help.

Hi.

I think that the best way to get started with OCL is using the examples provided by Ganymede eclipse distribution.

Push the menu option:

File -> New -> Example ... and take the EMF and OCL projects (one of these is the OCL console interpreter).

After that, when you execute the projects like RCP application or in a Runtime Environment, you have to create a model that follows the Ecore metamodel description.
On that model, push the right button of the mouse, and it will be shown a context menu in which is the OCL Interpreter option.
Now, you can write OCL expressions in that console and evaluate them against the model that you have created.
