Re: beforeRender() - Cannot modify component hierarchy during render phase?
what version of wicket is that code?
I guess 1.2? then you should use onAttach()
because onBeforeRender you can't change anything anymore because the page is
already rendering.

Re: beforeRender() - Cannot modify component hierarchy during render phase?
I am affraid you can't modify a component from a behavior before
render. Unline onBeforeRender in component, the behavior's
beforeRender is called right before component rendering, i.e. during
the rendering process. In the next verion we will probably rename the
before/afterRender methods in behavior and add onBefore/after render
method consistent with component's onBeforeRender/onAfterRender.
