Looping in JSF?
Hi,
I want to create list of commandButtons based on a collection of
ActionObjects. so I want to loop over my collection of this.
But I cant seem to find looping constructs in JSF except from the DataTable.
Does <c:forEach> work or how do I mix it with Java constructs in a JSP file
thanks for any hints

Hi,
Youre probably right. I fixed it in another way where I skipped the
attribute and hooked in the actionExecutionListener() to the Action
object and kept the wizard.actionExecution()
thanks anyway for your kind help!

Maybe this is due to the fact that you have a java attribute names not
following the convetions ("ID"), that can provoke problems when using
reflection. Can you try to use this and see what happens?
<f:attribute name="actionID" value="#{action.iD}"/> (note the i of iD
is lower case)
To see if this is what is happening, try to rename the attribute ID
from your Action class to "id" or "identifier", and try "#{action.id}"
or "#{action.identifier}.
Hope that helps!

Hi,
Thanks for the help. Found a followup problem, for some reasons the
attributes don't get propagated, below lAID is null in
actionExecutionListener?!
Map lAParams = event.getComponent().getAttributes();
Object lAID =lAParams.get("actionID");
<t:dataList var="action" value="#{wizard.actions}" layout="simple">
<h:commandButton value="#{action.label}"
actionListener="#{wizard.actionExecutionListener}"
action="#{wizard.actionExecution}">
<f:attribute name="actionID" value="#{action.ID}"/>
</h:commandButton>
</t:dataList>

data list should be your friend. With layout=simple there are no HTML
tags added, only the contents of the list. It has index and max count
properties as well that make it easy to work with.

using facelets you can use also c:foreach but I think that you can do
everithing also with t:datatable

Hi, have you tried the t:dataList [1] component in tomahawk? I guess
it does what you need...

I'm no expert on EL but what you are describing sounds like a good candidate
for a custom component.

Hi,
I want to create list of commandButtons based on a collection of
ActionObjects. so I want to loop over my collection of this.
But I cant seem to find looping constructs in JSF except from the DataTable.
Does <c:forEach> work or how do I mix it with Java constructs in a JSP file
thanks for any hints
