Jochen Theodorou commented on GROOVY-8956:
------------------------------------------
this should be:{code:Java}codeTotals["${it[1]}"] = (codeTotals["$it[1]"] ==
null) ? 0 : (codeTotals["$it[1]"] +=1){code}
> conditional if/else has issues with evaluated strings in maps

> Key: GROOVY-8956
> URL: https://issues.apache.org/jira/browse/GROOVY-8956
> Project: Groovy
> Issue Type: Bug
> Components: groovy-jdk
> Affects Versions: 2.5.0, 2.5.2, 2.5.4, 2.5.5
> Environment: Ubuntu, Sun Java 8
> Reporter: Owen Rubel
> Priority: Minor
>
> I was converting an if/else to a conditional and had the following error:
> class org.codehaus.groovy.ast.expr.TernaryExpression, with its value
> '((codeTotals[$it[1]] == null)) ? 0 : codeTotals[$it[1]]', is a bad
> expression as the left hand side of an assignment operator at line: 50
> column: 87.
> My if/else (which works)is as follows:
> if(codeTotals["${it[1]}"]==null){
> codeTotals["${it[1]}"] = 0
> }else{
> codeTotals["${it[1]}"] += 1
> }
>
> ... VS the logical conditional (which throws the error):
> codeTotals["${it[1]}"] = (codeTotals["$it[1]"] == null) ? 0 :
> codeTotals["$it[1]"] +=1
>
> Right now I am just trying to test some features but I thought this was weird
> enough to mention since a logical should work the same regardless of variable.
