Wizard in a dialog window does not show errormessages from the database

Question

I have a main window and some wizards defined with JHeadstart. The wizards are started as dialogs to get them in a separate windows from the main window. This gives me a cancel and a save button for the dialog in addition to the ones for the wizard.
I have managed to take away the cancel and save button from the dialog using custom .vm files. The problem is that then pressing the FINISH button for the wizard it closes the dialog window without showing errormessages from the database (ie constraint messages) and these only appear in the log. If I use the save button from the dialog it gives the errormessages, but does not exit the dialog even if there are no errormessages.
Is this a bug or is there another way I should have done this ?
The code for starting the wizard.
<af:commandLink id="StartVeiRegMerknad"
text="#{nls['TABLE_TITLE_VEIREGMERKNAD']}"
action="dialog:StartVeiRegMerknad"
useWindow="true" partialSubmit="true"
launchListener="#{DialogLaunchHandler.handleDialogLaunch}"
windowWidth="600" windowHeight="600"
returnListener="#{backing_show.backFromPopup}"
immediate="true">
<f:actionListener type="oracle.jheadstart.controller.jsf.listener.DoRollbackActionListener"/>
<f:actionListener type="oracle.jheadstart.controller.jsf.listener.ResetBreadcrumbStackActionListener"/>
<af:resetActionListener/>
</af:commandLink>

Answer 1

Your finish button should call a custom managed bean method that executes the commit, checks whether there are errors, and only close the dialog of there are no errors.
To close the dialog in code, you can use this:
AdfFacesContext adf = AdfFacesContext.getCurrentInstance();
adf.returnFromDialog(null, null);
which is similar to using the <af:returnActionListener/> that you probably now used but should be removed from your finish button.
