[jira] [Updated] (GROOVY-10073) Unable to use custom string representation in GString template

     [ https://issues.apache.org/jira/browse/GROOVY-10073?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gallyam Biktashev updated GROOVY-10073:
---------------------------------------
    Description: 
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}

  was:
