Struts2 Validation not working with theme simple
I have a very weird error.
I am trying to do a very simple basic validation like this example:
http://struts.apache.org/2.x/docs/basic-validation.html
However, If i have the following line in my struts.properties then the
validation stops happening and I do not see any errors.
struts.ui.theme=simple
I spent a very long time in researching which line in my
struts.properties file is causing this error.
Has someone seen something like this before? what is the best way to
resolve this??
Thanks!

Changing to show field error messages by hand would most likely entail
significantly more work.

How are you doing validation now?
In any case, I meant showing field error messages by hand by checking
the field errors map for specific field names, in the HTML/JSP, instead
of having it done by the theme.
Seriously--consider modifying the simple theme (creating your own theme
based on the simple theme) and adding the error message bits of one of
the themes that includes them. Otherwise you'll be adding either a chunk
of JSP to check for field errors, using a custom tag to encapsulate it
somehow, or something fairly similar.
How is it that the project got so far along that changing the theme is
too much work and nobody noticed that validation messages weren't being
displayed?

I'd expect it could be handled with an expression validator; whether or
not this is the cleanest solution is arguable. Once validation gets more
complicated than a single expression or two doing it in Java may end up
being easier to understand and maintain. There's no reason declarative
and programmatic validation can't be combined.

<s:fielderror/> worked fine. I was trying too many things so got confused.
I have one further question regarding validation. Is it possible to
validate a text field only when certain strings are selected from the
multiple drop down box.
Basically I want to make the text feild required only when some
strings are selected from the multiple drop down box, which is in the
same form as the text field. Can this be done via struts2 validation
or do I have to write a custom validator for this?
Thanks!

Are you saying the <s:fielderror/> tag doesn't render field errors in
the "simple" theme? The template file sure makes it look like it does.

by the way. I can do without having errors right beside the textfield.
I can have them grouped up top

Stop using the "simple" theme.
The "simple" theme tags don't display error messages--they're simple.
You'll either need to switch themes, show field error messages by hand
(if you want the messages near the fields), or modify/extend/create a
theme to emit the HTML you want.
At this time I cant afford to change the theme of the site. Because
that breaks the html on a lot of pages and would require a lot of
effort to correct those pages.
>show field error messages by hand (if you want the messages near the fields),
how can i do this? do you mean, by using field validators like on this
link? http://struts.apache.org/2.x/docs/using-field-validators.htmls
Appreciate your help
