Plugin XMI/UML-Export problems

Hi,

In our VP-Plugin we have a vp-action to export a model to xmi/uml. It’s basically the built-in export -function, but without the possibility for the user to set any options. For this we start the ExportXMI.sh-script, that comes with VP, with all our predefined parameters (Type: 2.1UML2, Encoding: UTF-8 ). This works fine but the problem is that the resulting uml-files are different from the ones we get when we start the export via the built-in function even with the same parameters.

How is that possible? Do you use the script for the export as well or is there an other way? And if so, can we use this way in our plugin (via OpenAPI)? Or is this a incompatibility/bug?

Thanks for your help!
