[Stripes-users] Writing to response.writer is not working
Hi everyone, I want to write an html page back to the user at the very beginning of an ActionBean submit method. The method calls a web service that takes around a minute to respond, and I want to put up a message before the web service finishes. I'm on Tomcat 8. I tried flushing the writer, but the page still doesn't display until after I return the Resolution from the submit method. Is there a way to make it write immediately?

Re: [Stripes-users] Stripes-users Digest, Vol 113, Issue 4
The link that Joaquin describes is not quite what I want either. I want to
allow the user to go ahead and
continue to work, not wait one minute before they can go on. This seems to
describe a scenario where a 'wait page' would be updated periodically, and
I don't want the user to have to wait at all. Sending an email from within
the action upon completion would work for me as far as notifying the user
about their form submission.
It appears to me that If I can get the response writer to write out my new
page at the beginning of the submission, it would satisfy my requirement.
How can I ensure that the writer is flushed?

Re: [Stripes-users] Flushing a writer before the ActionBean has completed
Thanks Remi, I'll give this some thought, this helps a lot.
Also, I did come up with a way to prompt the user at the beginning of the
submission.
I pop up a jquery-ui dialog box, instead of trying to use the response
writer
to write a new page.

[Stripes-users] Using an executor with Stripes, on Tomcat 8
Remi, from some of my reading, I'm getting the impression
that one should be careful when using threads inside of a
servlet container. How do you do this, can you elaborate?

[Stripes-users] making a wizard page
Hi Stripes users! I'm not able to setup a wizard that can navigate backwards when there's a validation error on the current page. I read the information about it, and I tried a @DontNavigate annotation on the method of the actionbean, but it still tries to validate. Can anyone tell me how to do it? I'd like a solution that allows going backwards with validation errors, AND retaining the information on the previous page. https://stripesframework.atlassian.net/wiki/spaces/ STRIPES/pages/492018/Wizard+Forms Backward Navigation Issues Backward navigation still presents a couple of problems. The automatic-wizard system that Stripes uses assumes that when a submission is made that either all the data on the page is valid, or the user will be shown error messages. Sometimes it may be desirable to allow the user to navigate back in the wizard without forcing validation of the information on the current page. This is a limitation of the current system. You have three choices, neither of them ideal: Use JavaScript to perform backward navigation. The downside to this is that by not submitting any data to the server, the user's entries on the current page (if any) are lost. Force the user to provide valid entries before performing backward navigation Don't use Stripes' built in required field valiation, but validate fields yourself based on what page is submitted -- Fear is a reaction, courage a decision - Winston Churchill -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot___ Stripes-users mailing list Stripes-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/stripes-users

[Stripes-users] multi-page forms ?
In the Portofino docs, the term 'wizard' is used to describe generating a web app from a database. Can Portofino generate a 'wizard form', a multi-page, multi-step form? -- Fear is a reaction, courage a decision - Winston Churchill ___ Stripes-users mailing list Stripes-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/stripes-users

I've implemented wizard forms in stand-alone stripes using this link: https://stripesframework.atlassian.net/wiki/spaces/STRIPES/pages/492018/Wizard+Forms I'm not familiar enough with Portofino to know, but maybe I can adapt that methodology.
