    reRender, update Model and commandLink

    Gledson Rabelo Newbie

      Hi,

      I'm using the Seam EntityHome and Ajax4JSF for developing ajax enabled CRUDs with pagination.

      The data table has checkboxs that the user can select to delete many entities.

      When I clicked in the Delete Button ("Excluir") the value of checkboxs should be updated in model, the method #{questionarioHome.removeChecked} should be cleaned called and the form should be cleaned reRendered returning to first page of data table, respectively .

      But, the values returned for #{questionarioHome.removeChecked} method are the values of first page and not of the current page.

      I thinking that the Rerender operation is being executed before the update of the model and the call the method #{questionarioHome.removeChecked}.


      I tried to use immediate=true in the commandLink, but the call of method #{questionarioHome.removeChecked} is executed before the update of the model and I don't get the selected values.

      I am making made a mistake?

      Please, could somebody help me?
