[jira] [Commented] (GEODE-7259) Function Execution Through REST API
Limitation
[ https://issues.apache.org/jira/browse/GEODE-7259?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16950906#comment-16950906 ]
Alberto Bustamante Reyes commented on GEODE-7259:
-------------------------------------------------
[~jjramos] is there any known limitation for not supporting nested collections? I would prefer to fix it instead of documenting the limitation

> Function execution through the {{REST API}} doesn't support nested collections as part of the parameters, this is an undocumented limitation.
> We basically try to convert the {{JSON}} parameters into a {{Map}} and afterwards, based on the {{Map}} contents and the {{@type}} value within the JSON string, convert that into the actual {{Object[]}} parameters expected by the function. If any of those objects contain an inner collection ([] as JSON) or object ({} as JSON), the initial parsing will always fail:
> {code:title=AbstractBaseController.java|borderStyle=solid}
> private Map<?, ?> convertJsonToMap(final String jsonString) {
> Map<String, String> map = new HashMap<String, String>();
> // convert JSON string to Map
> try {
> map = objectMapper.readValue(jsonString, new TypeReference<HashMap<String, String>>() {});
> } catch (JsonParseException e) {
> throw new MalformedJsonException(
> "Bind params specified as JSON document in the request is incorrect!", e);
> } catch (JsonMappingException e) {
> throw new MalformedJsonException(
> "Server unable to process bind params specified as JSON document in the request!", e);
> } catch (IOException e) {
> throw new GemfireRestException("Server has encountered error while process this request!", e);
> }
> return map;
> }
> {code}
