I need to minus some value from a fixed number in jsf

Question

I need to minus some value (value coming from DB though Databean and VO) here is my code:

value="200 - #{pc_costReportDataBean.adjustCostVo.explanationLength}"

but the problem is result coming like [200-0].

Answer 1

Try:

value="#{200-pc_costReportDataBean.adjustCostVo.explanationLength}" 

The #{} means that the whole expression inside will be evaluated. The values outside will be just treated as Strings.
