Mark Struberg commented on MYFACES-2827:
----------------------------------------
MyFaces latest from SVN
OWB latest
juel EL-2.2
<h:selectBooleanCheckbox
rendered="#{courseAnnouncementOverview.showApprovalIcon(course) }"
value="#{courseAnnouncementOverview.selectedCourses[course.id]}" />
The problem happens if the selectedCourses Map doesn't contain the key. In this
case the course.id (a Long) get's returned (not sure if this is backed by the
EL spec though...)
> CCE if component values are not of type String
