The tank-info-delegate cast its model to CylindersModelFiltered, since this is what the equipment-tab uses since implementing the filtering of unused cylinders. However, the planner users the same delegate and still uses the unfiltered CylindersModel. This means that the (dynamic) cast returns a null pointer and crashes. One possibility would be to derive CylindersModelFiltered and CylindersModel from the same class that defines virtual functions and cast to that class. This is a different attempt: don't cast (i.e. stay with a QAbstractItemModel and play it via Qt's model-view system. Firstly, replace the passInData function by a role to setData(). Secondly, read the working-pressure and size via new columns using data(). Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
