I'm trying to export my whole project through the option ExportPLCopenXML. It seems working, but when I'm trying to import the xml I have the following error during the importation process:

Object reference not set to an instance of an object.

It seems a usual issue with this process that affects to the pointer to user classes inside a procedure. I receive this error for two general functions that have this pointer declarations in the VAR_INPUT section.

It seems a bug into the export/import process of CodeSYS and I couldn't skip it so far.

Anyone could help me? Thanks in advance.
