Peter Štibraný commented on STS-730:
------------------------------------
Example JSP code: <stripes:options-map map="${actionBean.availableOptions}"/>
Where
{noformat}
Map<Integer, String> ActionBean.getAvailableOptions() {
return ImmutableMap.of(
1, "Option 1",
2, "Option 2");
}
{noformat}
> Support google collections ImmutableMaps with stripes:options-map

> Key: STS-730
> URL: http://www.stripesframework.org/jira/browse/STS-730
> Project: Stripes
> Issue Type: Improvement
> Components: Tag Library
> Affects Versions: Release 1.5.1, Release 1.5.2
> Environment: any
> Reporter: Nathan Feger
>
> google's collections API makes for a very novel way to make immutable maps:
> http://code.google.com/p/google-collections/
> http://google-collections.googlecode.com/svn/trunk/javadoc/com/google/common/collect/ImmutableMap.html
> Map:
> public static final Map<String, String> MAP = new
> ImmutableMap.Builder<String, String>()
> .put("abc", "xyz")
> .put("key2", "value2")
> .build()
> However, when the tag attempts to read the key and value out of the
> ImmutableEntry class (that extends Map.Entry) it throws an exception:
> 2009-12-08 11:00:46,817 ERROR [http-8080-Processor25]

> are surprisingly nice to work with.
