Struts + JavaScript = dynamic forms
I d like to write a form with, say, 3 dropboxes. Choosing an option in 1. box changes list of available options in other 2 boxes. [Eg. box #1 can store list of countries and box #2 list of cities in chosen country, or all cities if no country is chosen.] It can be done with JavaScript. However, I am looking for your opinion about Struts-way of doing that task. -- Pozdrawiam, Janek Ziniewicz gg: 902858 irc.freenode.net: #gore, #dub - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: SimpleDispatchAction error
I probably have found an error. It needs short description. Each of ActionForms in my app uses two Action classes. One is 'typical' form launched after submitting a form. Its execute method forwards to next Action which sets data for new form before displaying it. [..] --> PreAction1 --> ActionForm1 --> Action1 --> PreAction2 --> ActionForm2 --> [...] Now, I guess that all actions generate GETs/POSTs. My logs prove it. Submiting a form proceeds without an error if its method=="GET". With POST I still get it. Everything would be fine if I could use only GET method. My question is, how can i get rid of this 'multi submit' error? I use PreActions mainly for prepopulating data in new form. Maybe there is some other nice way to do it?

Re: SimpleDispatchAction error
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?

Dealing with many forms
Hi, I am writing my first Struts application, and have some problems with it. Some part of my app, gets data from database, fills appropriate form, displays it and, if user changed the form, writes data back to database. Another functionality is: get whole webpage (including form)from database, fill it with data and if user changes it, write changed data back to database. It was done with Jsp and JavaScript. Writing ActionForm for each form would be senseless because part of functionality of the app is that any user can submit new forms. And now the problem: Some devices do not deal with JavaScript well (some palmtops, cellphones etc). And my app must run properly on them. So, is there any way to do the task above without JavaScript? -- Pozdrawiam, Janek Ziniewicz gg:902858 irc.freenode.net: #gore, #dub - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
