[news.eclipse.tools.gef] Re: problem with flowLayoutEditPolicy

["Hao Zhang" <bjzhanghao@xxxxxxxx>]

Hello Randy:
I want to use FlowLayoutEditPolicy with ToolbarLayout, but it throws a
ClassCastException. I have to override isHorizontal() to avoid this, now it
works fine. I wonder if it it the proper way.

Regards
Hao
