Hi, I've been trying to solve a problem I have using qooxdoo for over 3 months now with no luck. Any assistance modeling this properly using qooxdoo would be helpful.
Basically, I have a 3-tiered tree of data organized as follows: Composer \-> Piece1 \-> Movement \-> Movement \-> Movement \-> Piece2 \-> Movement \-> Movement \-> Movement and so on. However, to avoid taking up all of the available memory and performance, the structure starts out as: Composer \-> Piece1 \-> Loading... and then I lazy-load the movements as needed. In a separate location, I store a program consisting of 3-4 pieces and their movements that uses a Composer's/Piece's/Movement's ID to link back to the tree above. I've designed a control that displays the composer, piece and movements and allows editing them, which can then be used in a qx.ui.form.List to display the program. Each of the three things is displayed using some kind of list (selectbox or List) My problem is that no matter how I organize it, I can't get 3 controllers to properly bind together. Thus, when the user changes the composer, the piece controller and the movements controller should update their models based on the composer's children. Sometimes, and with no apparent pattern, no events are fired at all (as determined by adding a listener on the composer's list controller). On a refresh, the same conditions occur, but I can't find anything that is making the event not trigger, because when I step through with firebug, an event is always triggered. When I stopped using binding and instead tried to monitor change events, the same problem occurred: no events fired sometimes. How should I be solving this? I need it to work ASAP, it's the last thing holding up a major release.
