Parameter 1 not being set

Question

Hi everyone,
I'm trying to delete a row from a data table and although I'm using a simple piece of code which works elsewhere I'm getting a parameter1 not set error. The problem is with cursorFirst() but I haven't got an idea why...
Anyone got a suggestion?
Thanks very much in advance...

Here's the code -
try {
log("Into the prerender about to set parameters");
editRanges_RangesDataProvider.cursorFirst();
log("**********at ranges data provider first cursor**********");
editProducts_firstRange = editRanges_RangesDataProvider.getValue("RANGES.RANGEINFOID");
log("**********got rangeinfoid**********"+editProducts_firstRange);
editRanges_rangesDD.setSelected(editProducts_firstRange);
log("**********just set rangesDD**********");
getSessionBean1().getEditRanges_RangesRowSet().setObject(1, editProducts_firstRange);
log("Just set parameter 1");
editRanges_suppliersDataProvider.cursorFirst();
editProducts_firstSupplier = editRanges_suppliersDataProvider.getValue("SUPPLIERS.SUPPLIERID");
editRanges_supplierDD.setSelected(editProducts_firstSupplier);
getSessionBean1().getEditRanges_suppliersRowSet().setObject(1, editProducts_firstSupplier);
log("Just set parameter 2");
} catch (Exception ex) {
log("Couldn't set parameters", ex);
Here's the error -

I will answer for someone looking for this answer. Actually I'm working on a search page. If you want to use CachedRowSetDataProvider for your searching page, using a parametric query on a Session Bean, then you have to add some code to the page where you have your table (or working on), defining some values in order to avoid this error. In other words, setting the parameter values at the beginning.
In my case, I'm searching over a patient's table using 3 parameters.
    public void prerender() {
     if ( this.fldCriteria.getText() == null ) {
          try {
               // This code runs the first time but not for postback requests.
               pacientesDataProvider.getCachedRowSet().setObject(1, "XX");
               pacientesDataProvider.getCachedRowSet().setObject(2, "XX");
               pacientesDataProvider.getCachedRowSet().setObject(3, "XX");
               pacientesDataProvider.refresh();
          } catch (Exception e) {
               error("Cannot set initial search value " + pacientesDataProvider.getValue(
                    "nombres"));
               log("Cannot initial search value " + pacientesDataProvider.getValue(
                    "nombres"), e);
    }You may want to use other values, it depends on what kind of data are you working on.
I hope this info helps somebody else, as help me to finish my project.
