<div dir="ltr"><div>Hi,</div><div><br></div><div>I came across an interesting case in the HV user forum [1], where a user is essentially nesting messages parameters within an EL expression:</div><div><br></div> ${validatedValue > someValue ? '{x.y.z.message}' : '{x.y.w.message}'}<div>
<br></div><div>The expectation is that at first the two message parameters are resolved and then based on the conditional expression the outer EL expression either resolves to one message or the other.</div><div><br></div>
<div>This is currently not supported in HV, but reading the interpolation algorithm in the spec [2] I can't find anything indicating that this case would prohibited. On the other hand I'm not sure whether we intentionally meant to support it (at least it never occurred to me); if so, I think we should provide an example for this in the spec.</div>
<div><br></div><div>The use case seems valid to me, also for cases where one wants to refer to constraint attributes in conditional logic. Any thoughts?</div><div><br></div><div>--Gunnar</div><div><div><br></div><div>[1] <a href="https://forum.hibernate.org/viewtopic.php?f=9&t=1029782">https://forum.hibernate.org/viewtopic.php?f=9&t=1029782</a></div>
