GmfMap allowed types for metric expression [message #783890]

Hello!

I've created a gmf editor and I've notice the Metric Container in the .gmfmap file. I would like to use this to expose some metrics, such as counts and percentages. When the ocl expression returns a integer, every thing works well, but if it's a double an error is thrown saying that is not possible to cast from double to integer.

It seems that this metric expression only allow integer types. I was hopping there is some file in the gmf editor project that i could modify to suport double types.

Does anyone knows how to do this?

Hi,

can you identify where the class cast exception happens? You could use the stack trace for this. The place of the generated code is of interest for you. Try to fix it there. If this I can help you to modify the templates in a way that this does not happen again.

I'm sorry Ralph, I should have put here some feedback. I found the file that parse the MetricRule in the gmfmap (KAOSStandardMetricProvider.java), and in fact every ocl query is cast to double, or it seems so.
So I think my problem is in the ocl queries. I'm revisiting them and see if they are all correct.

Hi again,

Now something strange is happening. I have three metric defined. At the star of the gmf editor instance every metric is correct. If I make Edit->Metrics, the second metric change to zero, this with the same nodes and links. If i change the position of the second metric with the third, everything seems fine, even after I make Edit->Metrics, and again with no alteration to the diagram.
Does anyone have an idea to why this is happening?

I think the problem is that my metrics are based upon some operations defined into the Ecore. Does this make any sense? Because many of these errors disappear if I put the body of the operation instead of calling that operation.
