Subject Re: image submit and lookupDispatchAction - drives me struts

hi robert!

that's really nicely written code.
I'm not completely sure, why it does what i think it does though:
 you limit, which methods should get called in the struts-config, right?
(by specifying a list of the allowed buttonnames in the mapping)
 then you check if there is a [buttonname].x in the request which fits, right?
this indicates the button [buttonname] has been pressed so you dispatch to
lookup with [buttonname] as lookup key

so what is the intention for limiting the methods to the specified set?

if i change it to ignore the dynamic part of the button name it should work
for me; i should add some regexp lookup, maybe :)

thanks,
axel
