Error on Page Data Extractor: java.lang.IndexOutOfBoundsException: No group 1

[paul.ma...@gmail.com]

Hi,

I'm trying to use the Page Data Extractor plugin, but I'm having a lot of trouble.

I'm generating an HTTP Request, and the response data  is something like this:

STATS-APPLICATION=TOMCAT LB2<br/>
STATS-TOTAL_REQUESTS=34<br/>
STATS-ACTIVE_SESSIONS_COUNTER=19<br/>
STATS-TOMCAT LB2-ACTIVE_REQUEST_COUNTER=1<br/>

The values configured for Page Data Extractor are:

Chart Label:      (STATS-TOMCAT LB.*-ACTIVE_REQUEST_COUNTER)=
Regular Expression Value Extractor:  STATS-TOMCAT LB.*-ACTIVE_REQUEST_COUNTER=(.*?)<br/>

(I'm trying to get the value for STATS-TOMCAT LB2-ACTIVE_REQUEST_COUNTER)


The labels seems to be catched correctly because the GUI show me the valid options in the ROWS tab. But the values are wrong.
And when I open the Log Viewer, I'm getting this exceptions:

I tested the REGEXP agains this: http://regexpal.com/ and it seems ok.

My Jmeter Version is 2.9.

What could I've been missing?

Thanks.
