Trying to make a facelets template containing a dataTable

Question

i'm trying to make a facelets template containing a dataTable. i have several problems, but first i'll show you how i wrote the template, simplified of course (the final template contains much more):
<ui:composition>     
<h:dataTable value="#{tableSource}" var="#{vaar}" binding="#{tableBinding}"  id="#{faceletId}">
<ui:insert />
<h:column>
    <h:commandButton action="#{modifyAction}" id="modifyButton" value="Modify" />
</h:column>
</h:dataTable>
</ui:composition>ok, this was the template. now i'll show you how i'm "calling it" in my page:
(simpleColumn is another template i made, which works -has no problems)
<xyz:myDataTable tableSource="#{mainBean.jobsList}" tableBinding="#{mainBean.jobsTable}" vaar="job"
          faceletId="jobsListTable"   modifyAction="#{mainBean.actionTodo}">
<xyz:simpleColumn headerTitle="Nume job" faceletId="jobName" fieldValue="#{job.name}" />
</xyz:myDataTable>ok so here are my problems:
1 - i write "#{job.name}" to add a column with that value, but i get an error that the property "name" does not exist in type java.lang.String.
how do i fix this? i understand the problem ("job" is not defined as a variable, but as the simple string) but i don't know what to do
2- i write "#{mainBean.actionTodo}", and the function actionTodo() certainly exists in that bean, but i get an error that the property "actionTodo" is could not be found in that bean (i guess it's looking for a property, not a function). but why, it's in the "action" property of a submit button, so it should not be this way. how can i fix this?

Answer 1

seeing your answer, i don't think you've used facelets. the id's are not the issue here, they work fine. and besides, they're not variable.
i'm asking about the other two issues. what's the part that you don't understand? there isn't any more code than this, other than the template for xyz:simpleColumn, which isn't important anyway, since it works ok.
