compare 2 string while one does an int operation returns error

[erikmarbad]

I am performing the following operation:

$F{ANO}.equals((Integer.parseInt($F{ANO_ACT})-1) + "") ? $F{CAN} : new BigDecimal("0")

where $F{ANO} is a String variable and $F{ANO_ACT} is another variable of type String but that I must convert to an integer to be able to do an operation with it, the part after the ? Ok, the problem is in the comparison, any idea why I get this error:

net.sf.jasperreports.engine.JRException: net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression for source text: $F{ANO}.equals((Integer.parseInt($F{ANO_ACT})-1) + "") ? $F{CAN} : new BigDecimal("0")

Note: I am using version 6.18.1 of Jaspersoft Studio Community

Variables ANO and ANO_ACT cannot be null  and must be evaluated. 

Expression:  $P{ANO}!=null? ($P{ANO}.equals($P{ANO_ACT}!=null ? (Integer.parseInt($P{ANO_ACT})-1+""): "ANO_ACT is Null")?$V{CAN}:new BigDecimal("0")): "ANO is empty"
