app crash on selecting "Cancel" option on a menu

[rashmi_ghai]

Hi,
The problem I'm facing is that I have a menu with various options.These options are switched off/on as required.The menu options are associated with the left soft key and the right soft key is always "Cancel".
In only one particular screen, when i select the "Cancel" soft key the application crashes.The "Cancel" soft key works file on all other screens. Could anyone suggest a reason as to why this might be happening.
Below is some code for the menu resource.
---------------------------------------------------------------------------------
RESOURCE EIK_APP_INFO
{menubar= r_proinform_menubar;
cba = R_AVKON_SOFTKEYS_OPTIONS_EXIT;
}
RESOURCE MENU_BAR r_proinform_menubar
{
titles=
{
MENU_TITLE
{
menu_pane=r_proinform_options_menu;
}
};
}

RESOURCE MENU_PANE r_proinform_options_menu
{
items=
{
MENU_ITEM
{
command=EScanZoomCmdOnline;
txt="Online";
}
........................//more options
}
}

what is the cancel supposed to do there ?
is it possible to put a breakpoint into the function the cancel button is invoking, so you could figure out the excat line giving you the crash?
Also is there any error notes shoen during the crash ?
