Hi, Eelco,
Well... looking at the other filters, the key to this is getting the
ContainerInfo from the Markup, since ContainerInfo has a getLocale()
method.
The best example of this is WicketMessageTagHandler, whose constructor
requires the ContainerInfo in its constructor:
public WicketMessageTagHandler(final ContainerInfo containerInfo)
The WicketMessageTagHandler is instantiated in
MarkupParser.initializeMarkupFilters():
final MarkupResourceStream resource = markup.getResource();
if (resource != null)
{
final ContainerInfo containerInfo = resource.getContainerInfo();
if (containerInfo != null)
{
if (WicketMessageTagHandler.enable)
{
appendMarkupFilter(new
WicketMessageTagHandler(containerInfo));
}
....
}
....
}
If I could also inject this into the constructor of my filter, I'd be
set!
This could be possible if we changed
protected void initFilterChain()
{
}
to
protected void initFilterChain(ContainerInfo containerInfo)
{
}
(or if we added in that method to the api)
That way, I'd just need to sublcass MarkupParser.
wdyt?
