Hi thanks again I think I'm on the right path now. The whole naming thing is not a big deal i just made a model that reflects the names exactly from the xml. Maybe in a later point I can try to figure out how I could change this. For now I made a new model and a store with an xml proxy. I'm able to load the whole data into the store.
And my store
name: 'id',// Every model must start with an id of type int
So now I need to copy this in an store with a model that has the type sqlitestorage?
Again thank you so much for your help I really appreciate it!
