Scheduling EG projects breaks the relation to list data

[deleted_user]

I am having difficulties with scheduling projects in EG.
What happens is that the relation between the last dataset and the list data(report) breaks when the projects closes. It works fine the first time, then the project becomes corrupt the next time I open it because of the broken relation. I have tried using both permanent and temporary libraries with the same error result. I am using information maps as the data source.

Just to let you know,
This error occured when using PDF as output, and when the dataset was empty.. When using html this is not a problem.
