An example can be found in the test below:\r\n\r\n```\r\n    @Test\r\n    void testBrokenPredicate() throws Exception {\r\n        JSONObject json = new JSONObject(\"{\\\"vendor\\\":[{\\\"name\\\":\\\"kwik\\\",\\\"number\\\":1},{\\\"name\\\":\\\"kwek\\\",\\\"number\\\":2},{\\\"name\\\":\\\"kwak\\\",\\\"number\\\":3},{\\\"name\\\":\\\"kwak\\\",\\\"number\\\":4}]}\");\r\n\r\n        @Nonnull final JsonNode jsonObj;\r\n        try {\r\n            jsonObj = new ObjectMapper().readTree(json.toString());\r\n        } catch (IOException e) {\r\n            throw new APIException(e, \"JSONata failed during reading of json\");\r\n        }\r\n        Expressions jsonataExpression = Expressions.parse(\"vendor[name=\\\"kwak\\\"]{`name`: `number`}\");\r\n        Expressions brokenJsonataExpression = Expressions.parse(\"vendor[name=\\\"kwek\\\"]{`name`: `number`}\");\r\n\r\n        JsonNode result = jsonataExpression.evaluate(jsonObj);\r\n        JsonNode brokenResult = brokenJsonataExpression.evaluate(jsonObj);\r\n\r\n        // The brokenResult does not apply the grouping as expected\r\n        JSONAssert.assertEquals(\"{\\\"kwak\\\":[3,4]}\", result.toString(), true);\r\n\r\n        // Here we can see the actual result\r\n        JSONAssert.assertEquals(\"{\\\"kwek\\\":{\\\"number\\\":2,\\\"name\\\":\\\"kwek\\\"}}\", brokenResult.toString(), true);\r\n\r\n        // I expect this to succeed as seen here https://try.jsonata.org/ZkhsVPArq, but it fails\r\n        JSONAssert.assertEquals(\"{\\\"kwek\\\":2}\", brokenResult.toString(), true);\r\n    }\r\n```\r\n\r\nPlease let me know what I'm doing wrong or if this is a known issue.","author":{"url":"https://github.com/daanp","@type":"Person","name":"daanp"},"datePublished":"2024-06-21T13:02:28.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/312/JSONata4Java/issues/312"}
