    Default Pagination with RPC

    Pagination with RPC


    Using GWT RPC mechanism to load data in grid with pagination ...
    It is giving following error ....

    Also Like to mention that I am using https protocol to access my application.
    Does it make any difference?

    HTML Code:
    [ERROR] Uncaught exception escaped

    I'm afraid GWT is "lying" to you about that. Sometimes I've seen the same problem but was never related to BasePagingLoadConfig.

    It's probably the objects inside BasePagingLoading, the definition of your service interface / implementation, or any other object that GWT cannot serialize.

    I can tell you that BasePagingLoadConfig works fine with GWT RPC

    What object is your model object extending?

    I get this error as well, my model extends BaseModel and implements IsSerializable.
