> I recently began to audit a Struts 2.3.16.1 application that I am maintai=
ning. While running the pages through the HTML markup validation test at ht=
tp://validator.w3.org/=2C I noticed a problem: Struts 2 seems to automatica=
lly generate id=92s to many elements related to forms=2C and sometimes this=
 results in a page that has several elements with identical auto generated =
id. This then leads to a markup validation error. So far the only way I hav=
e found to get around this is to explicitly generate own unique ids=2C but =
this feels like a stupid solution. Is it not possible to prevent Struts fro=
m auto generating ids to forms and some elements within them?

> I have tried to google for some solution but have found nothing useful. I=
n case it matters=2C the application in question uses the basic Struts =94s=
imple theme=94 globally=2C but the same problem occurs also with the "xhtml=
 theme".

MG>reference for id is here
http://www.w3.org/TR/html401/struct/global.html#adef-id

MG>the 'functions' the (generated) id plays are illustrated here:
The (unique) =0A=
id attribute has several functions in HTML:
=0A=
=0A=
As a style sheet selector.As a target anchor for hypertext=0A=
links.As a means to reference a particular element from a script.As the nam=
e of a declared OBJECT element.For general purpose processing by user agent=
s (e.g. for identifying fields=0A=
when extracting data from HTML pages into a database=2C translating HTML=0A=
documents into other formats=2C etc.).    =20
MG>struts generates HTML tags using themes which means you *can* create a c=
ustom theme as seen here
<constant name=3D"struts.ui.theme" value=3D"mkyong" />
http://www.mkyong.com/struts2/working-with-struts-2-theme-template/

MG>If you *dont* want to create a new custom theme you can refactor existin=
g xhtml.ftl to set id=3D""
MG>can you indicate why you want to disable Struts generation of id for HTM=
L tag?
MG>if set id=3D"" then you would disable references to 'id' so the id refer=
ence would not resolve?
