Binding multiple JSF dataTables to view

Question

In order to get the row numbers of a datatable I got an answer here that I could bind the dataTable directly to the view (JSF 2 dataTable row index without dataModel).

I'm using that function in a composite component and there may be several of those in the same page. I believe that the binding makes it impossible to use more than one component on each page; is it possible to bind each table "separately" somehow?

Well you will bind each table on different managed bean, or on different properties of backing bean? Why would it be the problem? — partlov, Feb 04 '13 at 14:29

Create a backing component class with an UIData property.

@FacesComponent("fooComponent")
public class FooComponent extends UINamingContainer {

    private UIData table;

    // +getter +setter
}

And bind it to #{cc.table} instead (the #{cc} refers the current backing component instance).

<cc:interface componentType="fooComponent">
    ...
</cc:interface>
<cc:implementation>
    <h:dataTable binding="#{cc.table}" ...>
        <h:column>#{cc.table.rowIndex + 1}</h:column>
        ...
    </h:dataTable>
</cc:implementation>

Just noticed that I'm not able to use cc.table.RowIndex inside p:commandLink: – nivis Feb 04 '13 at 15:54
Easier to use ui:repeat. – Neuralrank Mar 08 '15 at 00:49
@Neuralrank: It appears that you've misread the question. The question asks explicitly about a data table. – BalusC Mar 09 '15 at 07:47
@BalusC: Although your answer to the question is correct I believe it's not likely to be the best solution to the OP's actual problem. – Neuralrank Mar 13 '15 at 03:49

Just use ui:repeat instead, it has built in support via varStatus.index.

I doubt that the OP is aware that this functionality exists in ui:repeat. – Neuralrank Mar 13 '15 at 03:53
