Claus Ibsen resolved CAMEL-24920.
---------------------------------
Resolution: Fixed
> camel-core: the ternary operator cannot take a compound condition (&& or ||
> inside ${ })
> ----------------------------------------------------------------------------------------
>
> Key: CAMEL-24920
> URL: https://issues.apache.org/jira/browse/CAMEL-24920
> Project: Camel
> Issue Type: Improvement
> Components: camel-core
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Major
>
> {{$\{a > 0 && b < 10 ? 'x' : 'y'\}}} is refused:
> {noformat}
> Logical operator && needs a predicate on the right hand side, e.g.
> ${header.foo} == 'bar'
> {noformat}
> Parentheses do not help either - {{$\{(a > 0 && b < 10) ? 'x' : 'y'\}}} is
> refused the same way. A single comparison is fine, so {{$\{header.n > 0 ?
> 'positive' : 'negative'\}}} works.
> So the ternary accepts a condition, but only a comparison: any real condition
> has to be lifted out of the braces, and outside the braces a {{?}} and a
> {{:}} are literal text, so the ternary cannot be written at all. The only way
> out is a choice EIP or a bean.
> That is hard to defend on its own terms, and it is a small gap next to the
> larger question of operators inside {{$\{ \}}} in general (a separate issue,
> with the analysis behind it).
> Tested on 4.23.0-SNAPSHOT.
