Paging issues using a dynamic view object...

Question

I am working on an application that uses JAG to generate JSP pages, i had the requirement to use dynamic view objects where the view object query is generated at runtime. The rest of the application is more or less the same... I used the defult functionality provided by TableScrollButtons.jsp file for paging. Now the problem im facing is that while the '>' and '<' buttons are working fine, i cant seem to navigate to the pages using the drop down...
With the default handler, whenever i select the range the range displayed remains the same ie 1-10, 10 being the rangesize, but the rows are refreshed with values from the next page. Also, if the next page is the last and is incomplete, then the rows are pushed in from the bottom, so that the last page is always full...I tried the tuning panel in the view object edit dialogue and all settings are fine (i think)...could anyone please tell me what i am doing wrong??

Answer 1

could it be because i am using a dynamic view object with dynamic bindings? i am using the preparemodel() method in the action as follows...
protected void prepareModel(DataActionContext ctx) throws Exception {
inferRangeBindingIfUnset(ctx);
ctx.getBindingContainer().setEnableTokenValidation(false);
String sql = ctx.getHttpServletRequest().getParameter("sql");
String cost=ctx.getHttpServletRequest().getParameter("CostCostCent");
String event=ctx.getHttpServletRequest().getParameter("event");
if (sql != null && event == null) {
setupDynamicQueryAndDynamicBindings(ctx,sql.substring(1),cost);
if (retrieveOnlyCurrentPageFromDatabase()) {
ViewObject vo = getIterForPaging(ctx).getViewObject();
if (vo.getAccessMode() != ViewObject.RANGE_PAGING) {
vo.setAccessMode(ViewObject.RANGE_PAGING);
// if(event==null)
super.prepareModel(ctx);
ctx.getBindingContainer().setEnableTokenValidation(true);
if (ctx.getEvents() == null || ctx.getEvents().size() ==0) {
setPage(ctx,1);
setLastPage(ctx,getIterForPaging(ctx).getRowSetIterator().getEstimatedRangePageCount());
else if(event.equals("setRangeStart")) {
setPageFromRequest(ctx);
}
