Subject Struts, xhtml & bad tag syntax ... maybe nice in 1.7
Date Tue, 24 May 2005 15:12:37 GMT
Hello,

Has anyone tried to make the struts tags xhtml compliant?  Here is what I
mean.

I have noticed that whenever an html component is generated using the html
tags (or any other tag from the libraries), they are usually not closed.

For example, when generating a form input field using:
<html:text property="whatever">

the html code generated looks like:
<input type="text" name="whatever" value="">

when it should really look like this:
<input type="text" name="whatever" value="" /> (Notice the / to close the
tag)

This is a problem when you want to enforce a specific DOCTYPE to your
web-application. The problem can easily be fixed... are struts developers
thinking about this problem?  It would be nice to have this addition to
Struts 1.7
