Description

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.
