hi,
i have a question concering the difference between EVAL_BODY_BUFFERED and
EVAL_BODY_INCLUDE.
if i understand correctly, the only difference is that EVAL_BODY_BUFFERED buffers the
output so that it
can be evaluated in doEndTag().
when i have a custom tag which extends BodyTagSupport (and so implements IterationTag)
jasper2 generates
the following code:
....
int _jspx_eval_tag_iterate_0 = _jspx_th_tag_iterate_0.doStartTag();
if (_jspx_eval_tag_iterate_0 != javax.servlet.jsp.tagext.Tag.SKIP_BODY) {
Cms mycms = null;
if (_jspx_eval_tag_iterate_0 != javax.servlet.jsp.tagext.Tag.EVAL_BODY_INCLUDE) {
javax.servlet.jsp.tagext.BodyContent _bc = pageContext.pushBody();
_bc.clear();
out = _bc;
_jspx_th_tag_iterate_0.setBodyContent(_bc);
_jspx_th_tag_iterate_0.doInitBody();
mycms = (Cms) pageContext.findAttribute("mycms");
}
do {
....
if my custom tag now returns EVAL_BODY_INCLUDE from doStartTag() the
variable "mycms" is only initialized at the end of the do { } while loop. the
TagExtraInfo specifies
"mycms" as VariableInfo.NESTED which means to me that between doStartTag() and
doEndTag() my variable
must be properly initialized.
why do i have to return EVAL_BODY_BUFFERED and not EVAL_BODY_INCLUDE from doStartTag()
to make my tag work?
this was not necessary in jasper1.
can someone please clarify the behaviour?
thanks in advance
