what is the difference between rich:column and rich:columns

Question

Can anyone tell me the difference between rich:column and rich:columns?

Answer 1

You are using rich:columns when you want to create columns dynamically

Eg:

<rich:columns value="#{dataTableScrollerBean.columns}" var="columns" index="ind">

    <f:facet name="header">    
        <h:outputText value="#{columns.header}" />    
    </f:facet>

    <h:outputText value="#{model[ind].model} " />

</rich:columns>

while you're using rich:column when you simply have a column in a rich:dataTable

<rich:column>

    <f:facet name="header">
        <h:outputText value="Price" />
    </f:facet>

    <h:outputText value="Price" />

</rich:column>
