I cannot reproduce your problem with the new release 7.8-0.7. Can you try again and confirm that it works now?

simschul commented 5 years ago

I still have the problems with the new release.

miq commented 5 years ago

Can you provide me the XML-File you are trying to open, so I can try to reproduce it here?

simschul commented 5 years ago

I send you an email. Github does not support .xml

simschul commented 5 years ago

I have just tried it again and now both saving and loading .xml stands works perfectly fine.

simschul commented 5 years ago

Ok just found out that this bug seems to be similar to Issue #6 : The above mentioned error can only be reproduced if you restart the program and then try to save/load a stand from/to .XML (before doing anything else). However, if you first (1) load a stand from an access database and (2) run simulations on this stand, the error does not occur.

miq commented 5 years ago

The problem still exists, reason being a missing stand location when loading.

miq commented 5 years ago

Now a new stand always has a (empty) stand location.
