see how Label works :)
class mycomponent extends webcomponent {
oncomponenttagbody(tag) { replacecomponenttagbody("<param
name='foo'>bar</param>"); }
}

Hi,
I want to create 2 components in my wicket application. The first one
would be a generic component for embedding any flash (SWF) content. The
second component would inherit from the 1st one and would be related to
a specific flash object we need to embedd in our business application.
Unfortunately, I cannot just use a Panel or a Include, because the tags
for the flash object must be dynamically generated. The application
needs to pass some dynamic values using flash variables.
I look forward for a very simple component that can generate markup, but
I can't find any. Based on many different examples I've found on the
Internet, I tried a lot of things: inherit from WebComponent, inherit
from MarkupContainer, override onComponentTagBody, override on Render.
All the alternatives produce the same error:

Does anyone have a simple example of how you create a simple component
to generate markup ? An example that works, I mean...
