Subject RE: [SOLVED] Default methodName for DispatchAction
Date Wed, 02 Jun 2004 18:56:12 GMT
I actually think I'm going to be able to get around the problem.
We're going to do new sort of browsing interface so I won't have to use the
form with multiple submits.
Thanks for all the help though, the tips will come in handy I'm sure.

You should look at the source code for the version of DispatchAction and 
LookupDispatchAction (available either from a download of src or the cvs 
repository).  Older builds just threw an exception if LDA didn't find a 
parameter for method.  You can overide the execute() but you might just 
as well write your own action. DispatchAction works differently.  Newer 
builds of struts have modified the behavior of LDA.

besides it is sort of fun to see how the things actually work.
