hi vamshi
in the controller of your supplier page go in in this way
in processRequest method
clear your VO like this
OAApplicationModule am1 = pageContext.getApplicationModule(webBean);
OAViewObject oav=(OAViewObject)am1.findViewObject("your VO");
oav.setWhereClause(null);
oav.setWhereClauseParams(null);
oav.setWhereClause("1=2");
oav.executeQuery();
and in
processForm request method set the where clause null again like this
OAApplicationModule am1 = pageContext.getApplicationModule(webBean);
OAViewObject oav=(OAViewObject)am1.findViewObject("your VO");
oav.setWhereClause(null);
hope this will resolve your issue
thanx
