Joe Germuska commented on WW-1517:
----------------------------------
Earlier, I asked:
Are there any extant tags which hold on to an additional Component
instance besides their "primary one"?
I'm still getting familiar with the architecture of the component tags, but it
kind of seems to me that it will be pretty hacky to use two components. If I
want to extend AnchorTag but also have a URL component then I kind of need to
construct the URL object in getBean(stack,req,res). I can do this, but it
seems like a "side effect" to requesting the bean. And if I'm not returning
the URL object, then I also need to replicate the dependency injection behavior
for the URL which is done for the "primary" component bean in doStartTag()
after getBean is called.
I am not saying I think it would be horrible to do this, but it's not that
elegant either, so especially because i'm new to the tag architecture, I didn't
want to act without input.
Also, since I can only extend one tag, I would have to duplicate the
"populateParameters()" behavior from URLTag to initialize my URL component.
Would it be crazy to have component beans have a populateParameters(Object
source) method? I am not sure I love that, but it crossed my mind as one
possible solution.

> Project: Struts 2
> Issue Type: New Feature
> Components: Views
> Affects Versions: 2.0.1
> Reporter: Ted Husted
> Assigned To: Joe Germuska
> Fix For: 2.0.x
>
>
> The url and param tags are very flexibile, but the most common case of a
> single parameter link.
> <s:url id="url" action="HelloWorld" includeContext="false">
> <s:param name="request_locale">en</s:param>
> </s:url>
> <s:a href="%{url}">English</s:a>
> is verbose (to the point of being silly).
> It is worthwhile to have a streamlined link tag, a al Struts 1, to cover the
> single-parameter case.
> <s:link action="HelloWorld" param="request_locale"
> paramValue="en">English</s:link>
> In the interest of brevity, I would suggest that includeContext default to
> "false" for the single-parameter case.
> Or, with a message resource key, from
> <a href="<s:url action="Login_input"/>">%{getText('"sign_on"')}</a>
> to
> <s:link action="login_input" key="sign_on" />
