Consider using AJAX in your application. AJAX is a good candidate when your app needs to behave like desktop applications. >To make this, I'm using javascript, but there are a lot of field values > and/or names extracted from the data base (codifiers, entities properties, etc), wired > to the javascript functions 'cause the page's performance depends on it (eg. if I select > the value "Admin" in a combo, I need to hide Table1 and show Table2, but if I pick > value "Operator" I need to hide both tables).

If AJAX is used wisely, business logic need not come into the view, also you can reuse the code. However AJAX primarily is JavaScript based. Check this out: http://javawebparts.sourceforge.net/ (see AjaxParts) Some articles on AJAX http://www.omnytex.com/articles/ Of course there are many other custom AJAX implementations as well. If you do not want use JavaScript and still use AJAX, http://ajaxanywhere.sourceforge.net There must be some good design patterns/ or guidelines when using AJAX. Has anyone here got some pointers to them?? > Any help is welcome, Thanks and Regards, Thomas Joseph Kott Software Pvt.
