Replying to myself, but without a fix.. I see at least one potential problem, in substituteExpressionLangauge():

Pattern pattern = Pattern.compile("\\$\\{(.*?)\\}");

That pattern will stop at my first '}'. I don't see an easy work-around at the moment.

We use the LiteUI and it is great that some properties allow an embedded parser (is it JEXL?). I need to customize subject displays, so I am using the property:


Unfortunately, it fails this simple test:

${if (true) { "hello"; }}

The Add member box in LiteUI says:

"Error searching for members: chudler, Error substituting string: '${if (true) { "hello"; }}'"

Does it even support conditionals? Does anyone have a link to the syntax for the version grouper is shipping with?

Would grouper-devs consider JEXL 2.0 at some point? It supports ternary operators and many other enhancements. However, it is not a drop-in replacement; Apparenlty, some API changes have occured. Yet a more active alternative is <>.
