logic:equal tag always evaluates the body

[David Alcoba <po...@hotmail.com>]

Hi,

We've a very rare problem with our webapp. We've a webapp running under an 
iplanet 6 (jvm 1.2) and struts 1.0

There's a simple jsp with a lot of logic:equal (they're not nested) and all 
of them eval the same attributed stored in the session. Something like this:

<logic:equal name="returnValue" value="0">
...
</logic:equal>

<logic:equal name="returnValue" value="1">
...
</logic:equal>

...

This code works fine but "sometimes" the body of all logic:equal are 
displayed. In the action we execute before showing this jsp we put in the 
request the "returnValue" and we print it in the logs too. When this rare 
situation happens the "returnValue" has always a correct value (0,1,..). 
Once time the logic:equal turns crazy there's no way to recover the normal 
behaviour. All the jsps don't evaluate correctly the logic:equal tags and 
the solution is reboot the server. No exception is throwed and the error log 
doesn't show any error.

Anybody know if exists some bug in struts 1.0 related with logic:equal tag? 
And is it possible to trace some logs when the method doStart is being 
executed in the EqualTag? We need more information to solve this problem.

Thanks,

David

Maybe when "sometimes" occurs, something in the first <logic:equals> has 
modified the value of "returnValue"?

If not, get out your handy-dandy debugger and enjoy!
