Not possible to attach 2 (or more) parameters from 2 different beans to an html:link?

2004-07-06 Thread Robert Bowen 
Hello listers. I sent an email about a week ago and haven't heard a blip. So I guess 
this simply isn't possible? If I have a bean user and another module and want to 
attach a property from each to an html:link tag, how do I do it?
 
As I understand it if I simply put paramName it will include ALL properties for that 
bean, which I don't need. But if I put paramName, paramProperty and paramId 
twice, once for each bean/property, it only attaches one!
 
Is there some way I can create a custom bean ... in the page, put the two properties 
I need inside it, and pass *it* to the html:link with paramName ?
 
Sounds kind a less-than.perfect solution. Any takers?
 
Thanks,
syg

You have to set a map of parameters to add to the link.

You may create the map in an action prior to your JSP, or use this in your JSP (if you 
use JSTL) :

jsp:useBean id=myLinkParams class=java.util.HashMap/

c:set target=${myLinkParams} property=param1 value=${user.id}/

c:set target=${myLinkParams} property=param2 value=${module.name}/

html:link action=/myAction name=myLinkParams

click me !

/html:link

If you use name, then you can just have a map of the params you need.
I have also been known to use forwards, and have the params in the forward definition. 
 That 
assumes that your params can be static.

  
 Is there some way I can create a custom bean ... in the 
 page, put the two properties I need inside it, and pass *it* 
 to the html:link with paramName ?

If you want to add multiple params to link, drop them in a Map. Here's an
example that also uses JSTL:

%@ taglib prefix=curi=http://java.sun.com/jstl/core;  %
%@ taglib prefix=html uri=http://jakarta.apache.org/struts/tags-html; %

jsp:useBean id=params class=java.util.HashMap/
c:set target=${params} property=userProp value=${user.userProp}/
c:set target=${params} property=moduleProp value=${module.moduleProp}/
html:link action=... name=params ...Hit me/html:link
