Hi There,

  In General you should not have to call a form submit yourself. The 
Rosa applet should do the submit for you. If you have a button (ex 
called ZOOM that does an action (example a point), set the 
TB_BUT_ZOOM_INPUT to parameter to auto_point.  Then the applet will 
store the coordinates in the variable defined by INP_COORD_NAME and will 
do the submit.

Are you using the applet with Mapserver ? Mapscript ?
