I have define a HTTP JSON Retriever Source and added a Set Point URL. This saves OK.
Data point definition saves and validates fine.
However, The when the "Settable" box and Set Point Name are configured saving the point returns an error.
Internal Server Error — java.lang.ClassCastException: class com.serotonin.m2m2.http.vo.HttpJsonRetrieverDataSourceVO cannot be cast to class com.serotonin.m2m2.http.vo.HttpRetrieverDataSourceVO (com.serotonin.m2m2.http.vo.HttpJsonRetrieverDataSourceVO and com.serotonin.m2m2.http.vo.HttpRetrieverDataSourceVO are in unnamed module of loader java.net.URLClassLoader @560513ce)
Any advice? Documentation is a little thin on this/
Version 3.7.1
