Stripes

• Type: Bug
• Status: Open
• Priority: Minor
• Resolution: Unresolved
• Affects Version/s: Release 1.4.2
• Fix Version/s: None
• Component/s: Tag Library

• Environment:

  windows xp, latest, java 5

Using the stripes-examples.war, expanded in Tomcat or some servlet engine, navigate to the bugzooky example web app, and bring up both Register.jsp and Register2.jsp in an editor. Copy the input tags for password & confirm-password from the second page, Register2.jsp, adding them to Register.jsp (also leaving them in Register2.jsp--the point is to load parameters before Register2.jsp is rendered; the use-case where this came up is actually a backward-navigation via a button labeled 'previous').

Next, add the "wizard-fields" tag at the TOP of the stripes:form in Register2.jsp (right after the tag opening). Run the app and enter some values on the first page. Click Next and then examine the HTML source for the page for the hidden fields added by the strips:wizard-fields tag.

Do you see hidden fields for values for the password and confirm-password?

Then edit Register2.jsp again, moving the wizard-fields tag to the bottom of the form. Hit the back button, refresh, and check HTML. This time, the wizards-fields tag has picked up the existence of the password/confirm inputs, and omits the relevant hidden fields.

Assuming replication, then using stripes 1.4.2, when the tag "wizard-fields" is placed before the input fields in a wizard JSP page, AND an actionBean field has a non-empty value, the tag seems to add hidden fields for even the bean-supplied inputs in the stripes:form. This duplication causes a contest between the hidden field's value and the input's value (and the hidden value wins in my testing, which is why I noticed this).

Conversely, if the wizard-fields tag is placed after the inputs within the stripes:form, all is well--no hidden field is added for any input that is already in the form.

BTW, consider adding a mention of the wizard-fields tag to the confluence page on wizards. It is mentioned only in old email:

http://stripes.mc4j.org/confluence/display/stripes12/mail/1539
http://article.gmane.org/gmane.comp.java.stripes.user/461/match=wizard+button

A possible blurb for that page from the javadoc for the tag is below.
--------
The stripes:wizard-fields tag examines the request and include hidden fields for all parameters that have do not have form fields in the current form. It will include multiple values for parameters that have them.

This tag is very useful for implementing basic wizard flow without relying on session scoping of ActionBeans, and without having to name all the parameters that should be carried forward in the form.

NB: put the stripes:wizard-fields tag at the BOTTOM of the stripes:form in Stripes version 1.4.2 and preceding, due to a bug.
