Re: How to dynamically initialize form:select ?
Hi Michael, > Or in other words: does struts allow for some convenient means > to initialize a page upon creation ? Some kind of PreAction ? I add a similar problem and requested for such a feature. Now, in Struts 1.0, you can use the ActionForm.reset(mapping, request) to fill your form with some values, before auto-population by Struts. Based on the request parameters or the mapping, you can detect if it's a first time initialization and do what you want. What can be disturbing is that Struts always comes after you and replaces your values with the request parameters values, but you shouldn't be concerned when you want initialization. If you're using version 0.5, bad luck! I did the move to 1.0 for that reason... Pierre Métras
Q: How to dynamically initialize form:select ?
Hi ! I'm slowly becoming familiar with struts. I'm now faced with the following problem: I have a form in the middle of my application which among other things sports a dynamically populated form:select. >From what I've read in the documentation I'm supposed to read the appropriate information upon Logon (or while navigating along the pages) and store in beans added as attributes to the session/request. While this certainly works I'm not yet fully convinced I'll like this for two reasons. 1) While the user moves along the dynamic info might change without it actually being used. This imposes IMO unnecessary load on the underlying DB which could and should be avoided. 2) For convenience and useability reasons the user can navigate the pages through some menus realized in JavaScript. While clicking his way through the decisiontree there is no interaction with the Servlet Engine. Eventually the user will come to a point where a full blown ActionForm/Action part is required which now need initialization according to the navigation done prior. Is there a way to achieve this other than creating some general helper-beans that solve this ? Or in other words: does struts allow for some convenient means to initialize a page upon creation ? Some kind of PreAction ? Thank you, Michael
