Dan,
I think that you may have better luck in a tag that doesn't actually extend or
particularly work around the write tag, but simply filters the results of body
content. That way your not just restricted to filering the content of a bean
property. Markup would be like...
<mylib:nl2br> whatever <nested:write property="something" /></mylib:nl2br>
...And in this would could get the advantages of nested tags or whatever form
you wanted. It also means you don't have to worry about blocking/supporting
the logic of any underlying tag.
The tag class itself would look like...
// import whatever
public class NL2BR extends BodyTagSupport {
public int doAfterBody() throws JspException {
if (bodyContent != null) {
String filteredContent = bodyContent.getString();
// filter here...
ResponseUtils.writePrevious(pageContext, filteredContent);
bodyContent.clearBody();
}
}
}
...this should, in theory, do the trick. No properties or anything, simply
filter whatever comes through in the body content.
Arron.
PS: get my mail the other day?...
email client plays funny buggers at times,
so I don't know what's sent and what's not.
