Hey!
I figured out how to access the model.
But first the question, if I don't move the data (so with Property Transfer) I can already do something about it, that SoapUI removes the backslashes. In the response they are still, in the properties after the transfer they are not. Maybe this would be the easiest way...
I now access the property with the name "id" as follows:
${=testCase.testSteps.get('propertyTeststep').id}
But the result in http log is:
[...] \"id\": org.mozilla.javascript.NativeJavaObject@403b554b [...]
But "id" should be the name of the property and the return the string id::number:"123" like a ${propertyTeststep#id} it does. Or I'm wrong?
