jsf 2 - Primefaces Process binding problems -
i trying create data table editable , dynamic collumns , rows. when try process table, values entered not being processed (they coming null).
i post codes below , hope can me figure out going on.
(the code posting part of whole code, not working)
i creating table using binding attribute:
<p:panelgrid columns="2"> <p:panelgrid columns="1"> <h:outputtext value="fornecedor" styleclass="headercolumn" /> <p:panelgrid columns="2" columnclasses="inputbotao"> <p:selectonemenu value="#{orcamentoaction.idfornecedor}" id="selforn" filter="true" filtermatchmode="startswith"> <f:selectitem itemlabel=" - " itemvalue="#{null}" /> <f:selectitems value="#{orcamentoaction.fornecedores}" var="f" itemlabel="#{f.nomeforn}" itemvalue="#{f.idforn}" /> <p:ajax event="change" /> </p:selectonemenu> <p:commandbutton action="#{orcamentoaction.addfornecedor}" icon="ui-icon-plus" process=":formex:pftable @this" update=":formex:pftable :formex:selforn"> </p:commandbutton> </p:panelgrid> </p:panelgrid> <p:panelgrid columns="1"> <h:outputtext value="produto" styleclass="headercolumn" /> <p:panelgrid columns="2" columnclasses="inputbotao"> <p:selectonemenu value="#{orcamentoaction.idproduto}" id="selprod" filter="true" filtermatchmode="startswith"> <f:selectitem itemlabel=" - " itemvalue="#{null}" /> <f:selectitems value="#{orcamentoaction.produtos}" var="p" itemlabel="#{p.nomeprod}" itemvalue="#{p.idprod}" /> <p:ajax event="change" /> </p:selectonemenu> <p:commandbutton action="#{orcamentoaction.addproduto}" icon="ui-icon-plus" process=":formex:pftable @this" update=":formex:pftable :formex:selprod"> </p:commandbutton> </p:panelgrid> </p:panelgrid> </p:panelgrid> <p:datatable id="pftable" binding="#{orcamentoaction.datatable}" /> -
