Simple theme and field errors
Working on first Struts2 project, and quickly found out that standard themes can produce some quirky output. (Hoping to write my own when I get some time). I decided to simply use the "simple" theme to give me the most control over HTML formatting. However, it doesn't display field errors from validation. So I tried adding this to jsp where I want the error message to pop up:
<s:property value="fieldErrors.fname"/>
... where "fname" is the field that failed validation. This works, but the error message always gets rendered back wrapped in brackets:
[You must enter a first name]
Of course, one could write some nasty code to strip out the brackets, but there must be an easier way.
Thanks for any help,
David

Csszengarden might be nice, but pretty ambitious. I just think that, if as I suspect, lots of people are rolling their own theme (which one almost has to in many cases), then having a place to put them would be helpful. I suspect there's a lot of wheel reinvention going on.

Often times just printing the .class of an OGNL expression can be handy in diagnosing issues without bothering with real debugging (or using the <s:debug/> tag).
There's no theme gallery I'm aware of, nor, I believe, are there too many TOGU (Themes of General Usefulness). They're not really themes in the sense of skins, although it might be nice to have a cleaned-up CSS theme and a csszengarden gallery; is that what you're looking for?

Jeez ... you'd think I'd be able to figure that out. Oh, well ... late night :-)
By the way, is there anything like a "theme gallery" for Struts2? somewhere to post new themes and view others' work?

There can be more than one error; it's a collection.
