Re: error messages lack debug information

2018-12-15 Thread Matthew Broadhead 
if i look at ValueExpression.getExpressionString it says 
#{cc.attrs.billTemplateSection.breakdown} which is a Boolean attribute 
of BillTemplateSection.  but it is saying it is not equivalent to 
BillTemplateSection.  is it possible to get a line number?
