Re: initialize Variables

[Pavel Gouchtchine <gu...@gmail.com>]

Hi All.
Can you, please, clarify how to use refName_matchNr?

My reg exp processor has the following params:

Reference Name: GROUPID
Reqular Exrpression: .value=\'(.*)\';
Tamplate: $1$
Match No: 1
Default value: ERROR_GROUPID

The response can bring me different number of ids. I am trying to get
group count via beanShell :

String groups_count = vars.get("GROUPID_matchNr");
print ( "Groups found "+goups_count);


return "Groups found "+goups_count;

It returns void all the time.

Please, help.

Thanks.
Pavel

The answer is in the manual:

Read the manual ...

matchNR is not set for Match No = 1
