...

with a bit debugging i realized, that the
"NestedMarkupWriter" in "renderIcon()" is a "NullWriter".
"NullWriter.getBuffer()" returns "null" and the
"Pattern" pEOL hates getting null as parameter.

i'm not sure wheather it is really a bug ( because of
the freaky ajax stuff ) and whether it can be fixed ...

thanks so far!

i have done a quick hack for that problem. i don't know
wheater it works in all cases, but maybe the author could
integrate something in this way.

thanks!
