Re: ClassCastException using the DynaValidatorForm
Don't you just love caching? The number of errors I have made like that which drove me insane until whatever it was - the browser, the server, the memory - stopped caching. Torture. Michael Muller wrote: That would explain it. The struts-config got re-loaded telling it that myForm was a dyna bean, but the re-serialized bean in the session was still one of my custom beans. Thank you! I had no idea that Tomcat serialized the session data when it shut down. -- Mike Wendy Smoak wrote: this resulted in the ClassCastException i described earlier, despite reloading the webapp and even restarting tomcat. Did you also close the browser window you were using to test? IIRC, Tomcat serializes session data when you shut it down. Just a guess, but I think you had a session sitting around with the old form bean, and since the name was the same, it got used. If you had changed the name from the beginning (myForm2) you likely never would have seen this. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: ClassCastException using the DynaValidatorForm
Bummer. It isn't so simple, judging from your stack trace. Looks like a config error, because struts is barfing when it tries to create your action form. Michael Muller wrote: All my fields are strings.

Re: ClassCastException using the DynaValidatorForm
I missed your second post. My mailer didn't thread it. So what is struts

I don't suppose it would be so simple as the wrong form specified in the
action mapping?

The name in action mapping needs to relate back to a name in the
form-beans configuration. So you should be able to change the name,
as long as you change it in both places. If you use the name
property in your html:form JSP tags, you have to change it there
also, although during the 1.1 development cycle this was changed so
that the html:form tag would look up the form bean from the mapping
found with the html:form action attribute.
You shouldn't be stuck with a foo form, but you may need to make
changes in more than one place.

Re: ClassCastException using the DynaValidatorForm
originally, i had a custom form bean with the name myForm and an
action with the same name.
i set up validation, and all was well. my form has oodles of fields,
however, so i figured i could save myself a load of development and
maintenance by using the dyna-form beans.
so, i created another form bean (a DynaValidatorForm) in my
struts-config. i named it myForm, and re-named the old myForm to be
foo so that i wouldn't have two forms with the same name.
this resulted in the ClassCastException i described earlier, despite
reloading the webapp and even restarting tomcat.
so i switched and renamed the dyna-bean foo and the custom form bean
myForm. things started working again.
THEN, i changed the name of the form bean used by the action to foo
(which is now the name of the dynamic from bean). to my surprise, that
works! and that's where i am now. functional, but confused.
i can hear the PHP guys snickering. :(

something other than a DynaBean is being stored where struts expects
to find a DynaBean.
Does this help anyone figure out what I'm doing wrong?

RE: ClassCastException using the DynaValidatorForm
this resulted in the ClassCastException i described earlier, despite reloading the webapp and even restarting tomcat. Did you also close the browser window you were using to test? IIRC, Tomcat serializes session data when you shut it down. Just a guess, but I think you had a session sitting around with the old form bean, and since the name was the same, it got used. If you had changed the name from the beginning (myForm2) you likely never would have seen this. -- Wendy Smoak Applications Systems Analyst, Sr. Arizona State University, PA, IRM
Re: ClassCastException using the DynaValidatorForm
That would explain it. The struts-config got re-loaded telling it that myForm was a dyna bean, but the re-serialized bean in the session was still one of my custom beans. Thank you! I had no idea that Tomcat serialized the session data when it shut down. -- Mike Wendy Smoak wrote: this resulted in the ClassCastException i described earlier, despite reloading the webapp and even restarting tomcat.

Re: ClassCastException using the DynaValidatorForm
Here's the struts source that's throwing the exception:
// Can we recycle the existing form bean instance (if there is one)?
if (instance != null) {
if (config.getDynamic()) {
String className = ((DynaBean) instance).getDynaClass().getName();
if (className.equals(config.getName())) {
Apparently, instance is not a DynaBean. It would appear that
something other than a DynaBean is being stored where struts expects to
find a DynaBean.
Does this help anyone figure out what I'm doing wrong?
