Calling infobus form from another.

Question

Hi
Here is a brief description of the problem.
A simple data form is created using JDeveloper2.0's wizard. It is an Infobus based dataframe,which has a simple gridcontrol fetching data from the dept table. This form is in the pacakge,
package1.
Another form is made with a master detail relationship between dept and employee table, in the package, package2.
Now a button control is added on the first form( which is in package1) and the following code is added to the actionperformed event.
void buttonControl1_actionPerformed(ActionEvent e) {
Frame f = new package2.Frame1();
f.show();
Essentially, it calls the form in package2 when the button is pressed. Once this action is performed, the login dialog box of the form in package2 appears. After which it throws the following error and shows a blank form.
DAC-405: SessionInfo: Application module creation failed; className: ConnectionTrade
JBO-00200: A Generic exception occurred during loading Customizations.
null
If I add a button in the second form, (ie. the one in pacage2 having a master detail relationship) and call dept form (in package1) from here, it works.
We are stuck with this problem, and unable to proceed with deploying the application. As each form need to be called and invoked from a menu.
Thanks in advance.

Hi,
You can do like this :
mainApplication(Menu)
+------------ Frame1
|
+------------ Frame2
In MainApp you call your frame, and remove from code the
windowListener of the frame. Replace the dispose(); in frame
methods fileExit(ActionEvent e) & processWindowEvent(WindowEvent
e), by try { finalize(); } catch (java.lang.Throwable ex) {
ex.getMessage(); }
It works great.
