[321tseug]

I added a file browser component to a dialog through 'User Interface->Dialogs', and added the dialog in 'Behavior and Logic->Sequences'.when the installation processed, I clicked the 'browse' button on the dialog,nothing happened, and i just found a exception in command line as below:

I just don't use the default file brwoser component.
I put a textfield and button to let the user select file.

add a listener on browse button:

public void buttonClickedBrowseImportBtn(com.installshield.event.ui.ISControlContext arg0)
{
JFileChooser chooser = new JFileChooser();
ExampleFileFilter filter = new ExampleFileFilter();
filter.addExtension("dat");
filter.setDescription("Data Files");
chooser.setFileFilter(filter);
int returnVal = chooser.showOpenDialog(null);
if(returnVal == JFileChooser.APPROVE_OPTION) {
try {
ISTextField oImportFileFeild = arg0.getISContainer().getTextField( "importFileField" );
oImportFileFeild.setText(chooser.getSelectedFile().getAbsolutePath());
}catch ( Exception e ) {
e.printStackTrace();
}
}
}
