--------------------------------------------------------------
I believe this is unrelated to GROOVY-2599 but instead is related to
GROOVY-9003/GROOVY-4653. The workaround would be to not implement List. You
might instead have a {{toList()}} or {{asList()}} method on the adapter and
possibly obtain the rendering you want and other functionality you need.

> URL: https://issues.apache.org/jira/browse/GROOVY-10073
> Project: Groovy
> Issue Type: Bug
> Components: Templating
> Affects Versions: 2.5.14
> Reporter: Gallyam Biktashev
> Priority: Major
>
> I have a class
> {code:java}
> class JsonListAdapter implements List {
> private final List<Object> adaptee;
> private final JsonNode node;
> public JsonListAdapter(List<Object> adaptee, JsonNode node) {
> this.adaptee = adaptee;
> this.node = node;
> }
> // methods here
> @Override
> public String toString() {
> return node.toString();
> }
> }
> {code}
> I'm expecting that it will work like
> {code:java}
> var json = "[\"v1\",\"v2\"]";
> var node = parseJson(json);
> var list = toList(node);
> var result = gStringTemplateService.render("${variable}", Map.of("variable",
> new JsonListAdapter(list, node)));
> // both assertions fail for now
> Assertions.assertNotEquals("[v1, v2]", result);
> Assertions.assertEquals(json, result);
> {code}
