Unknown Embedded

[David Sowerby]

I had started developing a component using gwt-graphics, copied
originally from the bar chart example, and seemed to be getting an
odd interaction with the Timeline component, so I reverted to the
original example to make sure I had not introduced a problem.

Although the example chart seems to work OK, in the ?debug console I
get this :

Widget set is built on version: 6.6.6
Starting application campus-1367741217
Vaadin application servlet version: 6.6.6

Unknown Embedded; no type or mimetype attribute

It seems that the "Unknown Embedded" message comes from VEmbedded, but
I cannot work out whether it matters or not, or how to prevent it if
it does

For reference, I looked at the Timeline component, but I cannot see
anywhere which would set the attributes used by VEmbedded, and
therefore prevent the message occurring - yet Timeline does not
generate the message.
