No enum const class com.google.wave.api.EventType.OPERATION_ERROR

[Piotr Pejas]

Hi everybody,
I am new to group and wave.

I wrote simple robot which listen to blip changes and append some html
if blip text match my regular expression and I get an exception when I
call appendMarkup on TextView, append method works but escapes html
and it's not what I need.
Am I doing something wrong or is it a bug?

My code:
transformer.transform(xml, result);
textView.appendMarkup(outputStream.toString());

and exception:
/_wave/robot/jsonrpc
java.lang.IllegalArgumentException: No enum const class

Since I don't have the full context of your code, I am suspecting that your outputSream.toString() is returning content that is unserializable to the client library.  Keep in mind that appendMarkup() can only handle <i>, <strong>, <em>, <b>.

Thank you for clarification in javadoc there is no info which tags are
supported, and exception also wasn't very helpful.
I've built dynamic widget to work this around.

Interesting... I had assumed that appendMarkup() could translate any
HTML tag that was already supported by the rich text editor
(underline, bold, supertext, strikethrough, etc).

Basically, when a robot replies to the Wave server with a set of
operations, these operations are performed by the Wave server. If an
error occurs while attempting to perform the operations, the Robot is
contacted again with an error event.

What you see in the log is the Wave Server letting you know that
something went wrong. The issue with the current Wave-Robot-API
library is that it is not able to decode the error, yielding to a
critical error in the log. This is what you see.

To get more information, you must enable the robot to log at a FINEST
level, and then look in the logs for more information about the error.
