             Summary: EVAL_BRIDGE does not support multipart PluginResults
                 Key: CB-12283
                 URL: https://issues.apache.org/jira/browse/CB-12283
             Project: Apache Cordova
          Issue Type: Bug
          Components: Android
    Affects Versions: 6.0.0
            Reporter: Jess Holle


When moving from Cordova 5.1.1 to 6.0.0 our multi-part PluginResult communication started failing (without any other changes to the application).  This issue goes away if we force use of ONLINE_EVENT rather than EVAL_BRDIGE mode.

Further investigation shows that with EVAL_BRIDGE multi-part PluginResults result in [""] being sent as the response data, e.g.:

cordova.callbackFromNative('Vuforia296582484',true,1,[""],true);

This is clearly wrong and a result of JsMessage.encodeAsJsMessage(StringBuilder) having no case for MESSAGE_TYPE_MULTIPART (nor any appropriate delegate to ensure proper handling).  Reviewing the 6.1.0 sources suggests this has still not been fixed there.

Given the switch of the default bridge mode on Android to EVAL_BRIDGE, this is a very serious regression and breakage of existing plugins.  This should either be fixed or the bridge mode reverted to ONLINE_EVENT once again.
