[GitBox <gi...@apache.org>]

dominikriemer opened a new issue, #463:
URL: https://github.com/apache/streampipes/issues/463

   When adding the this code to the declareModel:
   
   Alternatives.from(Labels.withId(ENABLE_GROUPING),
    StaticProperties.group(Labels.withId(GROUP_CONFIG),
    StaticProperties.singleValueSelectionFromContainer(Labels.withId(GROUP_ID_STREAM_1)),
    StaticProperties.singleValueSelectionFromContainer(Labels.withId(GROUP_ID_STREAM_2)))))
   
    
   
   the following error occurs when the UI tries to resolve the options:
   
   Caused by: org.apache.http.ProtocolException: Target host is not specifiedCaused by: org.apache.http.ProtocolException: Target host is not specified at org.apache.http.impl.conn.DefaultRoutePlanner.determineRoute(DefaultRoutePlanner.java:71) at org.apache.http.impl.client.InternalHttpClient.determineRoute(InternalHttpClient.java:125) at org.apache.http.impl.client.InternalHttpClient.doExecute(InternalHttpClient.java:184) ... 80 moreorg.apache.http.client.ClientProtocolException at org.apache.http.impl.client.InternalHttpClient.doExecute(InternalHttpClient.java:187)
   
    
   
   It seems that the variable this.pipelineElement in BaseRuntimeResolvableInput in the ui is not initialized correctly.
   
   All values of of the REST request in fetchRemoteOptionsForPipelineElement are undefined.
