Assertion result handling

Hello,

Within a project I have 2 test suites (A and B). Groovy TestStep (from B) calls REST TestStep (from A)

Project

   TestSuite A

       TestCase A

          TestSteps

            REST TestStep

   TestSuite B

       TestCase B

          TestSteps

             Groovy TestStep

When I run groovy TestStep and the REST server is not up (Connection refused) the assertions configured on REST TestStep (A) not setting the assertion's message or error status. If I open (double click) on the GUI the TestStep (A) first  and then run Groovy TestStep then I got the status. Why???
