Hi there, I'm trying to do a retrieve on an object with java because I am building a string dynamically at runtime to use as a path. I've used the retrieveByPath function to return a list of the objects I want to retrieve. I couldn't find a lot of clear documentation on this so I might be making a mistake in my code. Either its the code or the path. CODE : public class Java_RetrievePRUsByXPath extends UserAction<java.util.List<IMendixObject>> { private String XPath; private IMendixObject __InputPRU; private jobs.proxies.PropertyRentableUnit InputPRU; public Java_RetrievePRUsByXPath(String XPath, IMendixObject InputPRU) { super(); this.XPath = XPath; this.__InputPRU = InputPRU; } @Override public java.util.List<IMendixObject> executeAction() throws Exception { this.InputPRU = __InputPRU == null ? null : jobs.proxies.PropertyRentableUnit.initialize(getContext(), __InputPRU); // BEGIN USER CODE List<IMendixObject> list = Core.retrieveByPath(this.getContext(), __InputPRU, XPath); return list; // END USER CODE } STACKTRACE: An error has occurred while handling the request.
