Description of problem:
Designer allows users to add a variable with a whitespace in its name to the process definition. Validation doesn't show this as a problem, process can be saved and project can be built. It shows up in the Deployments and in the Process Definitions, the process can be started, value is assigned to the variable.

The problem arises when user tries to open any kind of model - deployed process or instance or the process definition in the full Designer in the Authoring section. Designer never finishes loading and server log shows some errors.

The process I used to test this is a simple Start -> End with a process variable called 'some var' of type String.

Version-Release number of selected component (if applicable):
kie-wb 6.0 CR1
