The regexFunction is applied to the previous result in the test run.
However, as with other Configuration items, the User Defined Variables test
element is processed before any samplers are run.
Thus the regexFunction will not have anything to work on.
So I think the solution is either to add a Regex Extractor element as a
child of the sampler that has returns the session id, or embed the
regexFunction directly in the next sampler that needs to use it.
==
By the way, regexes are "greedy", in particular "(.*)&" will not stop at the
first "&" - it will continue until it finds the last possible "&".
To make it non-greedy, use the "?" qualifier, e.g. "(.*?)&". Or code it as
"([^&]*)&", i.e. 0 or more characters that are "not &".

I havent used this function before so if you cant get the following to work
then I'll try it out and investigate it.
>From the user manua it says:
Stored values are ${refName} (the replacement template string) and
${refName_g#} where "#" is the group number from the regular expression ("0"
can be used to refer to the entire match).
Therefore see what is in the variable ${getSessionId_g1}

The sessionid may not necessarily be all numbers. It
is a random string that contains letters and numbers.
In any case I checked to be certain and neither
${getSessionId} or ${sessionid} appear in the recorded
session and I see the full SessionID.
Is the __regexFunction meant to be used in the way
that I describe? Can I put the function in the Value
column in User Defined Variables in the Test Plan?
The regular expression is ok I think because I can use
the same expression in a Regular Expression Extractor
and it works.
