[Seam 2] Parameter,sent from EL expression in xhtml to metho

[fmars]

Because the beta 1 release has a bug, which makes my application not-runnable, i can't use it. So i built seam 2 from the CVS myself.

i have a stateful bean, a long-running conversation. In a step a table is displayed with clickable links made by <s:link>. from the "action" i'm calling a method of the bean with a parameter. The method is called successfully but the parameter is always null. I am using <rich:dataTable>. Here how it looks like (shortened)

<rich:dataTable var="gene" value="#{methcancerpipe.genes}">
 <f:facet name="header"> Column Headers ... </f:facet>

 <rich:column>
 <ui:repeat value="#{gene.geneinfo.isoforms}" var="isoform">
 <s:link action="#{methcancerpipe.displayCpGInfos(isoform)}" value="#{isoform.name} "/>
 </ui:repeat>
 </rich:column>
</rich:dataTable>

Somehow "isoform" set to null on the way. it is not null because the name (value="#{isoform.name} ) is shown correctly.

But if i set the parameter statically like this:

<ui:repeat value="#{gene.geneinfo.isoforms}" var="isoform">
 <s:link action="#{methcancerpipe.displayCpGInfos(methcancerpipe.genes[0].geneinfo.isoforms[0])}" value="#{isoform.name} "/>
</ui:repeat>

it works as expected. i think, this is a bug. What do you think?

There are some limitations on passing objects using EL, that is probably one (the variable isoform isn't available when the action is decoded). It's worth trying with a h:commandLink.

It's worth trying with a h:commandLink.

No, that's not working too, neither h:commandButton

I read the limitations again but still couldn't understand anything. Is there a workaround?
