When I get this error usually I get a blank line on the screen and onloy if I force a rerender of my JSF page the perf bar will suddenly appear. I am trying to figure out what I am doing wrong, Any help is appreciated.
SHould mention I am using JSF with Rcihfaces on JBOSS portal 2.6.5. SP1
with the B2 portal bridge. I am also doing the "Server Side" impl of the perf bar.
I get the issue about 1 out of every 10 usages. Others get it more.
