Hi everyone,
I've just started using Tomahawk, and JSF for that matter, and I have a
small problem.
My problem is as follows: I want to display a schedule with rows as
developers, columns as days, and cells as assignments. I can't use
h:dataTable, because the cells aren't actually cells, they can span up to 5
columns, this is because if a developer is working on the same project for
several consecutive days, then these consecutive cells are treated as an
"atom". Up to this point all works fine, my real problem is that I have a
master/detail scenario, I want to navigate to a modify page when an atom is
clicked. To achieve this I want to use component binding to have quick
access to the clicked atom.
Here is some relevant code:
<t:dataList binding="#{schedule.htmlDataList}" value="#{
schedule.resourceSchedules}" var="resourceSchedule">
<tr>
<td style="width: 200px">
<h:outputText value="#{resourceSchedule.resource.name}"/>
</td>
<t:dataList binding="#{resourceSchedule.htmlDataList}" value="#{
resourceSchedule.atoms}" var="atom">
<f:verbatim><td colspan="</f:verbatim>
<h:outputText value="#{atom.length}"/>
<f:verbatim>" style="</f:verbatim>
<h:outputText value="width: #{atom.length * 125}px;"/>
<f:verbatim>"></f:verbatim>
<h:commandLink
action="#{schedule.modify}"
rendered="#{atom.assignment != null && !atom.holiday}"
value="#{atom.assignment.projectName }"/>
<h:outputText
rendered="#{atom.holiday}"
style="color: #{atom.foregroundColor}"
value="N/A"/>
<f:verbatim></td></f:verbatim>
</t:dataList>
</tr>
</t:dataList>
First of all, I have a backing bean named schedule. It has two properties of
interest: htmlDataList and resourceSchedules. htmlDataList is binded to the
outer t:dataList, resourceSchedules is of type List<ResourceSchedule>. A
ResourceSchedule instance is used to represent the schedule of a single
developer (a row), it has several properties of interest: resource
(represents the developer), atoms (is of type List<ScheduleAtom>, represents
the cells, which can span multiple columns), and htmlDataList (which is
binded to the inner t:dataList). The problem is with the binding of the
inner t:dataList, I get an error saying resourceSchedule is null. It seems
that only the inner t:dataList has a problem with #{
resourceSchedule.htmlDataList}, I can use it elsewhere without any problems,
for example, I can have <h:outputText
value="#{resourceSchedule.htmlDataList}"/>
just before the inner t:dataList tag without any problems.
What am I doing wrong? I haven't experimented with h:dataTable to see if
it's a Tomahawk issue, becuase h:dataTable cannot generate the markup I
need.
Here are the exceptions, together with stack traces.
I really hope that someone can help me.
Thanks,
Csabi
