Hi all,
I have a problem with the rendered attribute and buttons in a h:dataTable. I
have my list of entries (as in the listing). If I click on the "Edit" button
all is ok - I get the edit page.
| <h:form>
| <h:dataTable var="entry" value="#{entryList}"
rendered="#{entryList.rowCount>0}">
| <h:column>
| <f:facet name="header">
| <h:outputText value="Title"/>
| </f:facet>
| <h:outputText value="#{entry.title}"/>
| </h:column>
| <h:column>
| <f:facet name="header">
| <h:outputText value="Status"/>
| </f:facet>
| <h:outputText value="#{entry.status}"/>
| </h:column>
| <h:column>
| <h:commandButton value="Edit"
action="#{entryAction.edit(entry)}" />
| </h:column>
| </h:dataTable>
| </h:form>
|
Now I want to extend my table, that the button is only displayed if a status is
set to a value allowing the editing of the entry.
I tried to put the rendered attribute to the h:commandButton like
| <h:commandButton value="Edit" action="#{entryAction.edit(entry)}"
rendered="#{entryAction.editable}"/>
|
than only the allowed entries get a "Edit" button. But if I clicked on the
button the page is rerendered and the corresponding action is not executed.
After that I tried the s:button. Here the method is executed, but the parameter
is null in my method.
Has someone any hints or could help me solving this problem?
Regards
Marco
