SimpleDispatchAction inherits from Action class not from DispatchAction.
At http://wiki.apache.org/struts/StrutsCatalogDispatchActionImproved you
can read:
"You can use a dispatch action without requiring configuration of a
parameter attribute in struts-config.xml."
My problem is that each of my forms generates two POSTs with one click. I
am not sure if the error comes from SimpleDispatchAction although it
appeared when I 've started using it. Its code looks ok.
Error appears in second POST, when SimpleDispatchAction::execute tries to
get handler parameter from request. Request of second POST doesn't have
any attributes set by me. All of them are erased after first POST - which
is proper behaviour. I dont know where this second POST comes from.
Are there any 'typical' situations when one click generates two submits?

Implies that you either haven't defined the dispatch parameter or you
haven't supplied a value for the dispatch parameter. Have you checked
the API for DispatchAction, in particular the parts relating to the
"parameter" attribute of a dispatch action mapping.

Subject: SimpleDispatchAction error
Hello again,
all my action classes are derived from SimpleDispatchAction class.
After
submitting a form I am forwarded to desired page but always get a
following error. Logs of my app show that after each submitting to POSTs
are sent. First forwards me to next page, second produces an error. Any
ideas what is happening?
Source of StrutsCatalogDispatchAction can be found at
http://wiki.apache.org/struts/StrutsCatalogDispatchActionImproved but
almost for sure problem is not located in SimpleDispatchAction.
