Re[2]: Evaluating expression on my custom tags
Hello David,
You are right. I just found the
org.apache.taglibs.standard.tag.el.core.ExpressionUtil class when
looking on the c:out tag source code.
I am invoking it from my tag lib and it is working very well.
But this use of the ExpressionUtil class is ok ? Can I expect his
interface to be stable on the next releases of JSTL implementation ?
Or this can broke my code ?
Danilo.
