Resetting the logic in the Graph Builder

[ABraun]

Hi Tom,

I experienced similar things. The errors are caused when changing an existing graph. You can correct them by opening the xml file with a text editor and search for the .1

Mandatory source product (field 'sourceProduct') not set

I investigated this some more: The problem re-occurs every time you insert a new module into an existing graph and place it between two connected modules, and remove the old link respectively. This somehow adds the .1 in the source product tag in the XML file which makes the graph incomplete.
