[jbossseam-issues] [JBoss JIRA] Updated: (JBSEAM-4264) add ability to get current index from within e:worksheet

[Eric Jung (JIRA)]

     [ https://jira.jboss.org/jira/browse/JBSEAM-4264?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eric Jung updated JBSEAM-4264:
------------------------------

    Description: 
If you have a collection of items with an arbitrary count, there is currently no straightforward way to dynamically output the collection row-wise. Is there any way to add a varStatus attribute like c:forEach and ui:repeat have? I'm open to other ideas, too, like using a binding for e:worksheet, but that doesn't seem to help the problem.

Here's an example of what I'd like to do:

<e:worksheet name="#{messages.mySheet}" value="#{myService.someList}" var="d" startRow="31" varStatus="status">
  <e:cell column="1" row="#{status.rowIndex+1}" value="#[d.foo}"/>
  <e:cell column="2" row="#{status.rowIndex+2}" value="#[d.foo2}"/>
  <e:cell column="3" row="#{status.rowIndex}" value="#[d.foo3}"/>
  <e:cell column="1" row="#{status.rowIndex+1}" value="#[d.foo4}"/>
  <e:cell column="2" row="#{status.rowIndex+2}" value="#[d.foo5}"/>
  <e:cell column="3" row="#{status.rowIndex}" value="#[d.foo6}"/>
</e:worksheet>
