The right items are high lighted now but I get many of the following errors

 Error in msEvalExpression(): Cannot evaluate expression, no item index defined.

This only seems to happen when there are many classes in the layer.  Are these 
errors expected?


This would happen if you have classes with string constants (EXPRESSION "...") or regular expressions (EXPRESSION /.../), but you did not specify an ITEM in the layer definition (so MapServer has no attribute value to use in matching the expression).
