On tableView eventHandler when the F1 is detected from the user it opens a second stage with a comboBox and two buttons. If the user selects an entry from the comboBox and hits the first button then it writes the value of the selected var to a file, closes the second stage and returns to the first stage, where it opens the above file for reading, gets the variable from the file and stores it in the firtst column of the row of the table that was active when the user pressed F1. The parts of: stages, read/write to file, updating tableview all work fine, though when change the code and i try to apply service (task) the second stage doesn't show. In other words two stages are not in tune.
