Werner Punz commented on TOMAHAWK-1449:
---------------------------------------
Ok another issue here our renderer calls a utils class which does following:
//Try to find out by value binding
ValueBinding vb = component.getValueBinding("value");
if (vb == null) return null;
Class valueType = vb.getType(facesContext);
if (valueType == null) return null;
if (List.class.isAssignableFrom(valueType)) {
Well the main problem here simply is that mojarra gives back an object which
itself is a weak reference
the return value itself however is a list in mojarras case, I assume we have to
add
a check on the value if a check on the type fails here!
