I'm having a hard time using the freemarker syntax radio tag. This works fine:
<@s.radio name="cars" list=[ "ford", "toyota" ] />
But using a literal map does not:
<@s.radio name="cars" list={ "ford" : "mustang", "toyota":"prius" } />
The web page renders:
"freemarker.ext.beans.HashAdapter$1$1$1@7e29d49f" as both the value and label.
I experimented with various listValue parameters to no avail.
Other things I've tried that also don't work:
* Creating a map using OGNL syntax: list="#{ ... }" -- FM chokes on the # --
"expecting number" error
* using <@s.set name="carList" value="%{ #{ ... } }" />
If this is ever figured out it'd be great to note it in the examples section of
this document:
http://struts.apache.org/2.2.3.1/docs/radio.html (probably also the doc for
select)
As well as mentioning freemarker map literal particulars on this document:
http://struts.apache.org/2.2.3/docs/freemarker-tags.html
UPDATE -- After a few hours and checking of source code, I came up with this
solution:
<#assign cars = {'ford':'Fusion', 'toyota':'Prius'} />
<@s.radio name="cars" list=cars listKey="key" listValue="%{ getText( value ) }"
/>
I would have expected it to work without the listKey and listValue attributes.
If you have additional insight I'd love to hear it.
Thanks,
