Hello, i have an gwt UI with different Widgets on it, and i need to get Data from DB Tables into this widgets, i have two dropdownlist widgets one of them is related to another so that if i choose one category in the first dropdown then it has many subcategorys in the second dropdown, and i need to get this data from DB table with gwt rpc. There is tables for this dropdownlists in the db also. I can't understand what to do to get this data from db tables with this gwt rpc. Should i create methods with query in Impl, Service and ServiceAsync classes for getting data from db tables and then call this methods from EntryPoint class? Any suggestions would be appreciated.

Yes. If any of the dropdown selection values affect this query, you can pass those values as arguments to these method(s)
 
Don't get me started about those stupid light bulbs.
