Subject Re: JSON Property
Date Wed, 05 Jan 2011 09:22:04 GMT
I think its "bundled" with S2 but as a separate jar, so dont get mistaken.

i am a bit reluctant to share my code, which is old and bad, not that
because i am cheap or anything, its because there are better and
well-thought code out there (as in JSON plug in) and my code has lots of
things tied to my project (bad design......).

and you know what i just checked back on my tag code. I dont think i am
doing anything much different from what your doing. I siimply copied the
s:property tag code and replaced the output part of the code.

here is the part i replaced.....(my tag mimics the "property" tag)
try {
            if (actualValue != null) {
                if (!(actualValue instanceof String)) { //if String then
treated its as if in JSON format
                    actualValue = JSONUtil.toJSON(actualValue);
                }
                writer.write(actualValue.toString());
            }
            else if (defaultValue != null) {
                writer.write(defaultValue);
            }
        }
        catch (IOException e) {
            LoggerUtil.BASE_LOGGER.info("error ocurred while writing json: "
+ actualValue, e);
        }
