Hello,
could somebody please explain me, how I can accomplish an update of the
values from within a nested DataTable?
The Table is populated with a Collection of ArraysLists containing the
objects to be updatable,
The DataTable should look like as follows:
<h:form>
<h:dataTable value="#{student.skills}" var="index">
<h:column>
<h:dataTable value="#{index}" var="skillIndex"
rendered="#{not empty index}" headerClass="datatableHeader">
<h:column>
<h:outputText value="#{skillIndex.skill.name}"/>
</h:column>
<h:column>
<h:selectOneMenu id="lvl" required="true"
value="#{skillIndex.level}" ><!-- To be updated! -->
<f:selectItems value="#{res.skilllevels}" /> </h:selectOneMenu>
</h:column>
</h:dataTable>
</h:column>
</h:dataTable>
<h:commandButton type="submit" value="Save"
action="#{student.updateSkills}" />
</h:form>
-> That doesnt work - the old values are displayed again after invoking the
"Save" button.
Thanks
Dirk
P.S: Do I have to use the binding attribute? If yes - can someone point me
to a good starting tutorial for that? I cant find any (for me) useful docs
for that....
