Required attribute
Is there a way to change the required attribute value in textfield,
textarea, etc. from asterisk (*) to some other value like (required)?
I'm using Struts 2.1.6

You can change the labelSeparator, but the asterisk is hardcoded. It'd
probably be quite easy to copy controlheader-core.ftl and make the change for
your project.

Martin, it's there, likely via inheritance. I'm pretty sure it's available on
all UIBeans. As Dave and I mentioned, it's rendered in controlheader-core.ftl.
The required parameter is a boolean, and if true, will place an asterisk
between the label text and label separator. IMO, if it were requested that the
asterisk be configurable, I'd be somewhat against it. The behavior of adding
an asterisk seems to be specific to the xhtml theme, and it would be trivial
to copy the controlheader-core.ftl out of the jar and place it on the
classpath with something other than an asterisk... Adding another attribute to
a set of tags that already have so many for such an easy change is overkill
(of course, that doesn't stop someone else from making the change).

Thank you Dave.
That is the file I was looking for. Initially I looked in the
common-attributes.ftl and couldn't find it.

IIRC the "*" comes from the template file; it should probably be
definable. Check controlheader-core.ftl.
