On click action firing button master detail class run but not show GUI window?

Question

In swing based project i create a master detail class using wizard and populate J Table and create a button Record in another class and put object of master detail class in action listener of Record button.But when i click Record button master detail class run butt not show GUI window while when i run it as main class or run direct it run successfully and show GUI window and also show record from database.I am confused because other classes run on click Record button if i replace object of master client class with any other class but only master detail class not show GUI window.Here is code of two class one is master detail with name of BrRecord and other class which handle it with name of Balance.Thanks.
