[OpenSTA-users] OpenSTA crash/malfunction if certain alteration made to script

[<geo...@sm...>]

OS: Windows XP
OpenSTA 1.4.3

- After recording my script (simple one, just log into my web app), I use 
the single-step function of OpenSTA to play it back. The tool seems to 
work fine at this point during playback.
- I need to extract a "tokenId" from the body of one of the responses, 
store it in a variable, then re-inject that value back into a request 
later on. So I make the following changes to my script:

        CHARACTER*1024  TOKEN_ID                        !Inserted into the 
Definitions section
        ...
        Load Response_Info Body on 8    &                       !Inserted 
into Code section right after the GET URI command that should have the 
desired value in it's response
                Into TOKEN_ID &
                ,WITH 
html(0)/body(1)/table(0)/tr(0)/td(0)/table(0)/tr(0)/td(0)/form(1)/input(1):ATTRIBUTE:value(0)
        ...
        ,BODY "validatorOff=true&tokenId="+TOKEN_ID             !This is 
body of a later POST URI command that I altered to now use the variable 
instead of a static value

- Hit Save to save the script, go to Commander where I have a Test set up 
with 1 VU running the script only.
- When I attempt to single-step through this updated script, the upper 
part of the tool appears to be working ('Run', 'Step', 'Stop' buttons work 
and the URLs highlight as if they are being played), but the lower pane 
where I expect to see HTTP request/response details remains completely 
blank.

Note: I have tried many permutations of my script, though not documented 
here. This blank pane in the single-step tool has occurred a number of 
times, or I may get a windows message saying that "TestPlugin has 
encountered an error and must close".

Any advice would be appreciated. I can send the full script directly to 
anyone that wants to look at it.

Thank you,
