I have also gotten this error and it was not obvious how it happened
since the appropriate parameters were
where they were supposed to be. You need to think of weird causes like
double clicking a link that contains parameters or
some how the form is submitted twice, the second time the "command"
parameter is not initialized. If an action was bookmarked
you can also potentially have problems. I don't think this is a problem
of DispatchAction or any of its relatives, MappingDispatchAction etc. I
think it is a problem with a funky request.

Unspecified will be called if your "command" parameter does not exist.

Hello
I posted this question 9months ago but could not get any solutions.
I wonder if anyone can give me some clue now.
--------------------------------------------------------
My client reported that they have received this error only once.
Request[/app/Keyword] does not contain handler parameter named 'command'.
at org.apache.struts.actions.DispatchAction.unspecified(DispatchAction.java:222)
They tried to replicate the error to find the cause by doing the exact same
operation that
the user did, but they were unable.
I've been trying too but I can't figure it out.
I have the following code within a jsp:
.
.
<SCRIPT LANGUAGE="JavaScript">
<!--
var loadingflg = false;
function submitExecute(mode, frm, message)
{
if (loadingflg == false) {
if (message != "") {
if (!window.confirm(message)){
return false;
}
}
eval("document.forms[0]." + mode).value = frm;
loadingflg = true;
document.forms[0].submit();
}
return false;
}
-->
.
.
.
<html:form action="/app/Keyword" onsubmit="return false">
<html:hidden property="command" />
<html:button property="regist" onclick="return submitExecute('command', 'regist',
'Regist?');">Regist</html:button>
</html:form>
When you click the 'Regist' button it goes off and registers the data on the
screen.
I didn't use LookupDispatchAction but DispatchAction.
My struts-config.xml is as follows
<action path="/app/Keyword"
type="app.controller.KeywordAppAction"
name="KeywordAppForm"
scope="session"
validate="false"
parameter="command">
<forward name="success" path="/app/Keyword.jsp" redirect="false"/>
</action>
Struts ver is 1.2.9 and the user is using FireFox2.0.
I wonder why this happened?
The client has not gotten the same error since they reported it a couple of
weeks ago.
Just to avoid that the error happens again, I can override "unspecified" method.
But they wants to know the cause more than countermeasures.
Does anybody have suggestions?
Thanks
Sachi
