Parameter to dropdown

Question

Hi there,
I'm trying to pass a parameter from dropdown1 to dropdown2 and further from dropdown2 to dropdown3 and I'm using the auto-submit under first dropdown. Every dropdown has a different datasource.
So the first passing works fine. coding under public page1:
try {
settableRowSet1.execute();
settableRowSet1.next();
} catch (Exception ex) {
throw new FacesException(ex);
} // end try catch
under the dropdown1:
public void dropdown1_processValueChange(ValueChangeEvent vce) {
try {
attributetableRowSet.setObject(1, dropdown1.getValue());
attributetableRowSet.execute();
} catch (Exception e) {
log("person change exception", e);
error("Exception changing person id: " + e);
} // end try catch
The "attributetableRowSet" is the source under the dropdown2. Ok until here everythink is fine.
But when I now try to pass another parameter from dropdown2 to dropdown3 there occurs a problem.
the coding under dropdown2 is:
public void dropdown2_processValueChange(ValueChangeEvent vce) {
try {
z_dropbase_1RowSet.setObject (1,dropdown2.getValue());
z_dropbase_1RowSet.execute();
} catch (Exception e) {
log("person change exception", e);
error("Exception changing person id: " + e);
} // end try catch
z_dropbase_1Rowset is the data-source under dropdown3
When I try to execute the change on Auto-submit the error 505 occurs
Who can help me. Who has an idea how to handle this problem
Thanks in advance
