BPMN2.0 Diagram Validation in EA12

[HarryPlotter]

Hello EA Hive Mind.

This is kind of a follow-on to ye olde thread http://sparxsystems.com/forums/smf/index.php/topic,26399.msg206307.html#msg206307. We are refreshing a substantial BPMN model developed in previous projects across a number of years (and several EA versions).

Does anyone know of any bad outcomes from ignoring 'Project Browser position' warnings? For example, does it restrict BPsim? We know how to resolve the warnings, just want to judge if it's worth the time.

    Running BPMN2.0 Diagram Element's position in Project Browser Validator...   
        Warning: Either Element 'ACME (Pool)' is incorrectly positioned on diagram (E.g. does the lane fit inside the Pool? Is the Zorder correct?).   
        Warning:   Or Element 'ACME (Pool)' is at the wrong place in Project Browser. Valid places are: the sibling of the diagram, inside the Main-Pool (or its referenced Process).   
        Warning: Either Element 'Customer (Pool)' is incorrectly positioned on diagram (E.g. does the lane fit inside the Pool? Is the Zorder correct?).   
        Warning:   Or Element 'Customer (Pool)' is at the wrong place in Project Browser. Valid places are: the sibling of the diagram, inside the Main-Pool (or its referenced Process).   
        Warning: Either Element 'VAR (Pool)' is incorrectly positioned on diagram (E.g. does the lane fit inside the Pool? Is the Zorder correct?).   
        Warning:   Or Element 'VAR (Pool)' is at the wrong place in Project Browser. Valid places are: the sibling of the diagram, inside the Main-Pool (or its referenced Process).

    Validate Results: (0) error(s), (6) warning(s)

It's ignorable if you're drawing a picture.

You'll need to fix it for any process involving interpretation of the model. Specifically, that will include BPSim and exporting the model using BPMN 2.0 xml to another tool.

Thanks Simon. Is anyone aware of any others?
