QM 6.1.0 fails to load legacy model from QM 5.2.5 #19

Closed smartinou closed 10 months ago

I recently moved to QM 6.1.0 Linux, on Ubuntu 22.04LTS. It failed to load legacy models built with QM 5.2.5. When attempting to do this, I get a pop up error:

Luckily, I checked the release notes found here: https://www.state-machine.com/qm/history.html#qm_6_1_0 The note about the new xml element external_package caught my attention. My model has an external package (.qpm) file. I manually edited the .qm file to replace the tag: <package file="./gui.qmp"/> with... <extern_package file="./gui.qmp"/>

... and the model successfully loaded.

According to the Note section of the release notes under 6.1.0, this change should have been backward compatible, but it seems like it's not.
