Hi guys,
In page 106 of JSP 1.1 PR2 spec, there are two methods defined in the BodyTag
Interface:
doInitBody() and doAfterBody().
doInitBody(): Invoked before the FIRST time the body is to evaluated .....
<snip>.......
doAfterBody(): Invoked after EVERY body evaluation ...... <snip>....
My concern is this:
I would have found it useful if there were a method doBeforeBody() defined.
Is there a reason this method was not specified. The method only makes sense
considering the existence of doAfterBody().
I page 100 of JSP 1.1 PR1 spec, this method was specified in the Tag class. Why
was this method
removed from the spec?
The reason I wanted this method is that I make certain scripting variables
available to the body
of the tag. The value of this variable is re-calculated at the beginning of
every iteration of the body.
Consider a loop tag.
<custom:loop start="<%= startIndex%>" count="<%= count %>">
</custom:loop>
It would be useful for the tag body to know the current iteration of the loop.
If there was a doBeforeBody(),
I could set the value of the scripting variable in this method. Instead, I have
to set the value for next iteration
in the doAfterBody() method. Doing it in the doAfterBody works fine, but it
just doesn't seem elegant.
I am running on Windows NT, Orion Server version 0.7.9
Thank you very much,
