I am trying to use a c:if statement inside a ui:repeat tag.
However U cannot get the value of course.days while inside the if tag. It just always evaluates to empty.
<div id="schedule_wrapper">
<ui:repeat value="#{schedule.courses}" var="course">
<div class="course">
<b>#{course.shortTitle}</b> : #{course.subjectCode} #{course.courseNumber}-#{course.section}<br />
#{course.roomCode} #{course.buildingName} <br />
<c:if test="${not empty course.days}">
#{course.days} : #{course.startTime} - #{course.endTime}
</c:if>
</div>
</ui:repeat>
</div>
Any ideas how I can use the course.days variable inside the if statement?
Or an alternate way to achieve the same thing...
All of the other course.xxxxx value as pulling their values in.

Answer 1

Try to use inside your using a rendered to check your condition.
rendered="#{not empty course.days}" or #{course.days > 0} if days is a Integer
<div id="schedule_wrapper">
<ui:repeat value="#{schedule.courses}" var="course">
<div class="course">
<b>#{course.shortTitle}</b> : #{course.subjectCode} #{course.courseNumber}-#{course.section}<br />
#{course.roomCode} #{course.buildingName} <br />
**<ui:fragment rendered="#{not empty course.days}">
#{course.days} : #{course.startTime} - #{course.endTime}
</ui:fragment>**
</div>
</ui:repeat>
</div>

Answer 2

I found an alternate way to achieve this.
Instead of:
<c:if test="${not empty course.days}">
#{course.days} : #{course.startTime} - #{course.endTime}
</c:if>
I used:
<h:panelGroup rendered="#{not empty course.days}">
#{course.days} : #{course.startTime} - #{course.endTime}
</h:panelGroup>
I am still interested if this is possible with an if statement.
