ui：repeat中的数据表中的selectBooleanCheckbox

Question

I'm having some problem using multiple selectBooleanCheckBox in multiple DataTables in ui:repeat.

Something like this

<ui:repeat var="f" value="#{mybean.values}">
    <rich:dataTable value="#{f.values}" var="v">
        <rich:column>
            <h:selectBooleanCheckbox value="#{mybean.selected[v.id]}"/>
        </rich:column>
    </rich:dataTable>
</ui:repeat>

In the backing bean, in the selected map, I found the wrong ids.

Anothery strange behaviour is that when i sort the column using the sortBy attribute, it sorts all the column rendered.

I've found the bug on the jira

RichFaces JIRA

If I use the

<c:forEach />

tag instead of

<ui:repeat />

Is a little better (no sorting between tables, more values are right in the backing bean), but sometimes it's still wrong.

Any ideas?

Thanks,

Answer 1

Try using the a4j:repeat .

I often have problems updating values on the backend using Richfaces from within ui:repeat (although normally with a4j:commandLink/commandButton ).

EDIT: And do you have a well defined equals() and hashcode() for the Class that you are adding to the list/set?

I've resolved ordering the values, since I was binding to a Set. I've used the SortedSet. Thanks anyway.
