Design issue: forms and iterations on the same page
I'm trying to figure out a good design strategy for building a page that allows viewing, adding, editing, and deleting of administrators. At the top of the page I have the form itself: html:form action="screen_manage_administrators.do" name="AdministratorUserForm" type="com.somewhere.aproject.AdministratorUserForm" table tr thName/th td html:text property="userName" maxlength="16" size="16"/ /td /tr tr thPassword/th td html:password property="password" maxlength="8" size="8"/ /td /tr tr td html:submit value="Set"/ /td /tr /table /html:form Under that I want a list of existing administrators (there will probabl only be 5-10 admins, and definitely not more than 20): table tr thName/th /tr tr td me /td td html:link href="screen_manage_administrators.do?num=0"Edit/html:linknbsp; html:link href="do_administrator_remove.do?num=0"Delete/html:link /td /tr tr td myself /td td html:link href="screen_manage_administrators.do?num=1"Edit/html:linknbsp; html:link href="do_administrator_remove.do?num=1"Delete/html:link /td /tr /table If you enter in data that does not match an existing administrator name and submit it, it adds the administrator. If you click on the "edit" link of one of the administrators, it puts that admin's details into the edit form. If the administrator name matches an existing name, the data is updated. If you click on delete, it will ask confirmation and then delete the entry. My first question is: Is it a good idea to be placing all of this functionality in one page, or should I be spreading it to other pages? My second question is: How would I implement such a layout in struts? I can associate a UserForm object with the form, but how would I interpret which administrator data to load into the edit form (via the argument "num")? Should I be making a separate form object to provide the list of administrators and then iterate over that list? If so, how do I access 2 different ActionForms within the same page? Would I be better off making an ActionForm that contains all of the data for the edit form as well as the collection of administrator data? Cheers!

Re: Design issue: forms and iterations on the same page
Oops, just realized I used my mock-up page. The part showing the list of administrators will of course use an iterate tag =) 2003 3月 5 水曜日 11:39、Karl さんは書きました: I'm trying to figure out a good design strategy for building a page that allows viewing, adding, editing, and deleting of administrators.

Re: Design issue: forms and iterations on the same page
You may have a look to the display tag lib who provide an
really easy to use purpose for your use case.
I show you an sample code I use in my view I got :
%@ page session="true" %
%@ page import="org.apache.taglibs.display.test.TestList,
org.apache.taglibs.display.test.ListHolder,
java.util.List"%
%@ taglib uri="http://jakarta.apache.org/taglibs/display" prefix="display"
%
%@ taglib uri="/WEB-INF/struts-menu.tld" prefix="menu"%

I made a little mistake in my code but it's not really important for you ;)) ... form.setName(student.getName ()); - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
