Once in a while I came to feel that we are doing something wrong with adding
the * within the template. That given, how about reverting to a solely CSS
driven solution with the semantics of HTML5 required attribute?
So setting tag attribute
required="true"
would render as
<label class="requiredLabel">...</label><input class="requiredField"
required="required" ... />
Obviously,
required="required"
would be completely omitted if the tag attribute is false.
For backward compatibility, we could recommend the following css based solution
to re-gain the "*" suffix behaviour:

This sounds good to me!
To preserve backwards compatibility with 2.3.15.1 the same behavior could be
applied to {{requiredLabel}}.
There might be issues that old browsers don't support CSS {{content}}

> Key: WW-4188
> URL: https://issues.apache.org/jira/browse/WW-4188
> Project: Struts 2
> Issue Type: Bug
> Components: Other
> Affects Versions: 2.3.15.1
> Environment: All
> Reporter: mahendran
> Assignee: Lukasz Lenart
> Labels: struts-tags-required-attribute
> Fix For: 2.5
>
>
> we are using struts 2.0.5 and 2.3.4.1 in our applications. And we decided to
> migrate to 2.3.15.1 to get the security fixes.
> we use struts tags to render UI components and using 'required' attribute to
> get the '*' along with the components.
> In the version 2.3.15.1, the attribute required is dropped, and we need to
> change to requiredLabel to get the same effect, this increases
> migration&testing effort for a application which has 1000+pages
> Hence we require a backward compatibility for 'required' attribute in struts
> tags.
> Also nowhere in the migration document this information is specified. This
> makes the struts migration as block-box. Hence we require a proper migration
> document which should specify what are all the changes required in the
> application to migrate the struts.
> But we managed to get the '*' in UI by replacing
> UIBean.class,AbsctactUITag.class and struts.tld from 2.3.4.1 version.
