WicketMessage: Markup of type 'html' for component

[tshepler]

Can so one point me in the right direction for this error message? I keep getting it and don't know where to start to solve it. I am getting it quite a bit on what was once a stable application, and now I am getting it quite often in developer. I don't know where to start.
Thanks

This comes straight from Servoy. Not sure that you or I can solve this.
I would report it as a bug in the support system.
