Returning null for unresolved variables
When Blueprints Processor was not able to evaluate a variable, it would set its value to null. The expected behaviour would be to set the value to the default repres- entation in the formal notation as defined by Apache Velocity, which is a dollar followed by the name of the variable between curly braces. For example, if the value of the variable pnf-id could not be evaluated in runtime, its value would be defined as the string "${pnf-id}". The problem happened during evaluation of the variables that would be later sent to the template-meshing code for processing. The fix was to add a check before the value was assigned to the varia- ble; if the was not null, the assignment will happen normally. Otherwi- se, if the evaluation resolves to null, the variable receives the defa- ult value (string "${<variable name>}"). Besides the tests that were put in place to test the code changed for this fix, two tests were added to the existing test case of the templa- te meshing code, to act as regression test.
