[s2] IndexedProperties set via forms
Hi, all.
I have a question about using indexed properties. I need to have the
user upload some arbitrary (to be dynamically increased via Javascript
while the user is on the form page) number of files as part of a form. I
figured it makes sense to create an indexed property so that then I have
a List<File> in my action whose elements I can then store as needed. I
can't find anything in the documents about how to get Struts to fill in
indexed properties from forms, though. (Well, plenty of Struts1 results
come up, which is why I assume this is possible, but no Struts2
examples.)
So, the question is: what syntax do I need to use to tell Struts2 that
some form elements will all be part of the same property in the action?
Also, are there any inconsistencies between File upload form elements
and others (aside from the need to have the FileUploadInterceptor on
your stack)?
(I also thought maybe I could just implement RequestAware and then get
them all out of the map, but this seems cleaner if it's possible.)

}
public List<File> getDocumentFiles() {
return this.docContents;
}
public String execute() {
// Do some stuff with the files.
}
}

Wow, in the FAQs, even. My Google-fu is miserable.
Thanks/sorry.

http://struts.apache.org/2.x/docs/how-do-we-upload-files.html should
cover
what you're asking here, I believe.
