IMHO, I'd say EL is actually harder, but at any rate EL can't completely do what the nested tags can. Like anything recursive. I just had an email conversation with a developer in England that has an app which business data model is a very large data structure. Depending on the level and required feature of the interface, they just have an include file for nested markup at any given level. The root JSP page simply includes the level for the given point and away it goes, regardless of its place in the hierarchy, and it's all updatable to the server because the actual property is made behind the scenes. This is only possible with the nested context being passed in the request. I put an OO-JSP spiel on my site, and this appears to be an extreme implementation of it. I know they're not everyone's cup of tea, but it's a hammer that can hit some pretty wicked nails. Arron.

Make Nested-EL tags
--- Additional Comments From [EMAIL PROTECTED] 2003-10-17 07:45 ---
To make it clear for me, the EL takes the provided expression and simply
translates it. This is then intended to be evaluated into the nested context?
My expectation:
Taking this nested markup...
nested:nest property=firstProperty
nested:nest property=secondProperty
nested:write property=${param.propName} /
/nested:nest
/nested:nest
...and the param to be colour as above, it would make the following property
in the nested context...
firstProperty.secondProperty.colour
...and if the param value was ../something it would be...
firstProperty.something
I'm assuming that this is the intended behavior.
NOTE: before it hits any kind of realease it needs to be tested with the iterate
tag. This is the only nested tag that needs to manipulate the indexed and mapped
properties to have [i] or (key) automatically into the property. First
thoughts say it should be fine, but a test would be spiffy to confirm it.

Re: Nested-EL
David,
To give you a technical answer: Kinda.
If there was a way for JSTL to reach in and grab the info that the nested tags
are holding (IE Pass the contents of nested:writeNesting /) then I don't
think you would need Nested-EL. Or, if all of the nested tags worked like
nested:write / where it assumes you are trying to get the latest nested:nest
property.
I want to do nested:select but the select requires a property. Which the
best way for me to specify would be EL, because I don't always know what the
name of the property is going to be.
So, the plan is to pass in the name of the property through jsp:param which
EL can then grab:
nested-el:select property=${param.fieldName}
...
/nested-el:select
Alternatives are welcome...

Maked Nested-EL tags
Summary: Maked Nested-EL tags
Product: Struts
Version: Nightly Build
Platform: All
OS/Version: All
Status: NEW
Severity: Enhancement
Priority: Other
Component: Custom Tags
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
It would be nice to be able to use EL with the Nested tags.
This could be used when doing a jsp include and passing in the name of a property.
jsp:include page=selectComponent.jsp
jsp:param name=propName value=color /
/jsp:include
then, inside of selectComponent.jsp
nested-el:select property=${param.propName}
option.../option
/nested-el:select
I will attach a set of classes that implement the packages:
org.apache.strutsel.taglib.nested
org.apache.strutsel.taglib.nested.html

You are right, JSTL doesn't completely remove the need for Struts specific

I think for the purposes of this discussion, the next generation would be
JSTL plus the struts-el taglib and when we talk about the Struts tags, we're
really talking about the traditional, non-el tags.
So keep using the html:form and other Struts tag and consider migrating to
the EL versions if you are using JSTL.

- Enhancement of the html:link tag)
Perhaps this belongs on the user list, but I think it is relevant for
the discussion at hand. You all seem to regard all of the Struts taglibs
as one item, for which JSTL is an alternative. While this is certainly
true for the logic: and bean: tags, I have not seen a replacement for
the
html: form tags (that is, html:form and all the controls) in JSTL.
The user guide
(http://jakarta.apache.org/struts/userGuide/building_view.html#form_bean
s)
suggests we replace
input type=text name=username
value=%= loginBean.getUsername() /
with
html:text property=username/
Does the use JSTL camp prefer this,
input type=text name=username
value=c:out value=${loginBean.username}/
or am I missing some basic JSTL?
Shai.
PS: There is a documentation error there; the original JSP should be
input type=text name=username
value=%= loginBean.getUsername() %/
