Olá pessoal, sempre que tenho problemas eu procuro e acho aki…mais esse não encontrei nada ainda se alguem tiver alguma dica…
Estou tentando implementar em exemplo do PrimeFaces que esta no site utilizando ( DataTable + Filtering + Checkbox ), quando implemento o DataTable + Filtering utilizando um List…sem problema ele funciona, DataTable + Checkbox ok…tudo um blz…porem quando DataTable + Filtering + Checkbox a tabela carrega, consigo selecionar todos…até ai blz…o problema esta no filtro quando seleciono o primeiro Ok ele faz o filtro perfeito, selecionando o segundo ele não faz nada quando seleciono o terceiro e traz o resultado do segundo…valeu
segue o Código;
xhtml
<p:dataTable id="multiCars" var="car" value="#{tableBean.mediumCarsModel}" paginator="true" rows="10"
selection="#{tableBean.selectedCars}"
filteredValue="#{tableBean.filteredCars}"
filterEvent="enter"
first="1"
