RE: JSP Tag Life Cycle

[Pavel Brun]

I was looking at the book again and it does not have anything to do with the
extended support for the IterationTag or the new constants used in the
doAfterBody()
method.

After "doEndTag" is done, my tag appears to run again from the "doStartTag"
method
and onward. IT appears like the entire tag is evaluated again.

Any thoughts would be greatly appreciated.

thanks

Paul

yes...sorry...that is what I was referring too. The JSL TagLib lifecycle
diagrams.

If anybody has any ideas, I like to hear them.

Thanks

I think he is refering to JSP TagLib diagrams, I believe they can be found
in official JSP specification. The IterationTag has the ability to
re-evaluate the body. While the ability is interesting, I cannot answer
Pavel's question - when it is supposed to be used. OTOH, I (still) haven't
gotten into some serious JSP work.

Nix.

[Pavel Brun]

it is in my book called: JSP Tag Libraries produced by Manning, written by
Gal Shachor, Adam Chace,
and Magnus Rydin page 98.

I will see if I can get a scan of the image and provide it for the group.

Thanks

Which specific diagram (in which document) are you looking at?  I don't
see anything like this on the lifecycle diagrams in the JSP 1.2 spec.

JSP Tag Life Cycle

[Pavel Brun]

Hello all,

I was just looking at the JSP Tag Life Cylcle diagram and had the following
question.
The "doEndTag" flows into a decision block that states "use t yet another
time".

In what case is the tag re-evaluated (i.e., the decision block returning
yes)? I have
a tag that is somehow being invoked twice when I want it to be invoked once.

My "doEndTag" does return EVAL_PAGE and I wanted it to return that because I
want the
rest of the JSP page to be evaluated.

Any auggestions or answers would be helpful

Thanks

Paul
