[英]primefaces datatable with multiple row selection
I want to select multiple rows from a primefaces datatable, i followed the examples in the showcase , but no results 我想从primefaces数据表中选择多行,我按照展示中的示例进行操作,但是没有结果
here is my XHTML: 这是我的XHTML:
<p:dataTable id="tabJob" var="contenuJob" value="#{templateBean.contenuJob}" selection="#{templateBean.selectedRows}"
rowKey="#{templateBean.idJob}" style="margin-bottom:0"
scrollable="true" scrollHeight="250" rowIndexVar="rowIndex" >
<p:column selectionMode="multiple" style="width:16px;text-align:center" />
<f:facet name="header">
selectionner les colonnes
</f:facet>
<p:column headerText="#" style="width:3%"> #{rowIndex+1}</p:column>
<p:columns value="#{templateBean.colonnes}" var="colonnes" columnIndexVar="ind" id="col#{ind}">
<f:facet name="header">
<h:outputText value="#{colonnes}"/>
</f:facet>#{contenuJob[ind]}
</p:columns>
<f:facet name="footer">
<p:commandButton process="tabJob" value="valider" action="#{templateBean.validerSelection()}"/>
</f:facet>
</p:dataTable>
and in my ManagedBean: 在我的ManagedBean中:
private ArrayList<String> contenuJob,selectedRows;
.................
public String validerSelection(){
System.out.println("size de selectedRows ::"+selectedRows.size());
return null;
}
and the sop only returns 1 which is the size, i've already tried rowSelectMode="add" in the datatable but it didn't change a thing 并且sop仅返回1,即大小,我已经在数据表中尝试过rowSelectMode =“ add”,但它没有改变任何东西
正如Jaqen H'ghar所说 ,我更改为rowKey="#{contenuJob}"
,它的工作非常完美:)
