Thanks for your quick responds. I am able to list items using the
'Zend_Dojo_Form_Element_FilteringSelect' fields with 'autoCompleteDojo'
which outputs json in my controller action. What I need now is to understand
the following line of code so that I can supply the correct URL for the
filtering to work:
->setAttrib('onchange', 'dijit.byId("cityId").store = new
dojo.data.ItemFileReadStore({ url:
"/data/lookup/table/city/filterName/countryId/filterValue/" +
dijit.byId("countryId").value });');
The normal URL I use to output the list is: "index/sites" in the second
field and "index/region" in the first field.
Thanks alot for your help.
