Description of problem:
When naming a reusable process using "_" (i.e. test_sample_new), it is not listed under "Called Element" to the parent process.

I am unsure if it is really a bug or if it is the expected behavior... I mean it could be a kind of "reserved" sign as it is listing resusable processes that contains "." or "-" in their names.

Version-Release number of selected component (if applicable):
BPM Suite 6.1.x

How reproducible:
Always

Steps to Reproduce:
1. Create a main process with a Reusable subprocess node;
2. Create a simple process as "test_sample_new" (it can contain only a ScriptTask);
3. Create another process as "testSampleNew" (it can contain only a ScriptTask);
4. Back to the main process, click on "Called Element"...

Actual results:
It will list only the "testSampleNew";

Expected results:
It should list both processes, maybe?

Additional info:
A workaround would be to use "." or "-" or other sign.
