revision to the html:link tag

[Andre_Beskrowni]

currently there are two ways to add parameters when using the link tag.  you can
either:
(1) specify 1 parameter using the paramId/paramName/paramProperty/paramScope
attributes of the tag, or
(2) specify a Map of name/value pairs that the name and property attributes

method 1 is obviously limiting.

method 2 is kind of a pain in the butt if you want to include parameters with
values from multiple bean, etc.  i get really annoyed at the idea of having to
created an extra Map just to store some values to be used in a URL.

here's my proposal.  you can keep the previously mentioned methods of adding
parameters and add another that looks like the following example:


  
  
  
  click here


this would result in a link that look like this:


click here


i have written this tag combination for my use, and would be happy to pass it
along if you think it would useful in the struts taglib.  basically i used the
same link tag with 2 changes:
1) set the  in the tld to be "JSP"
2) moved construction of the url to the doEndTag method

the urlParam tag just sets creates a Map to store its name-value pairs, stores
it in the PageContext, and sets the parent link tag's name attribute to the new
Map.  (as a result, you need to remove this value from the PageContext in the
link tag's release method.)

this tag combination adds some handy new functionality, and is
backwards-compatible as well.

RE: Iterate -- Logic Tag

[Andre_Beskrowni]

while it's true that java iterators and enumerators don't provide an index when
you loop through them, how many times have you found yourself using a local
count variable that you increment inside the loop?  i've encountered it plenty.
i don't think it's an uncommon scenario.

recently, i've ended up using a solution similar to Michael's to keep a counter,
but this doesn't seem ideal to me.  if people are really adamant about keeping
the iterate tag as it is, maybe the alternative would to construct an
indexedIterate tag or something like that.  on the other hand, from looking at
the source code for the iterate tag, there's already a lengthCount attribute
that stores the number of iterations.  why not just expose that?
