Anthony DePalma commented on STS-849:
-------------------------------------
Yes it will work if I change my objects toString to return the id, but I can't
do that as a solution since our toStrings are used for debugging our
application elsewhere. But really, this is the job the typeFormatter is
supposed to be doing, and is doing for other tags like the checkbox. Its
probably been a subtle bug for a long time, I've seen alot of posts about
people having difficulty with radio buttons preselecting.

> Key: STS-849
> URL: http://www.stripesframework.org/jira/browse/STS-849
> Project: Stripes
> Issue Type: Bug
> Components: Tag Library
> Affects Versions: Release 1.5.6
> Reporter: Anthony DePalma
> Labels: binding, taglib
>
> I am using a custom population strategy that looks only in the request first
> and then for values in the tag itself. I've noticed that the checked
> attribute does not work for radio buttons if the value is a non-primitive
> object.
> For example, using an example Story and Category object:
> Story
> Long id;
> Boolean approved;
> Category category;
> Category
> Long id;
> String name ;
> The following tags work correctly with the checked attribute preselecting for
> both radio buttons and checkboxes:
> <stripes:checkbox checked="${actionBean.story.approved}"
> name="story.approved" value="true"/>
> <stripes:radio checked="${actionBean.story.approved}"
> name="story.approved" value="true"/>
> However, using a non primitive object such as category, of the following
> similar tags, only the checkbox tag works correctly:
> <stripes:checkbox checked="${actionBean.story.category}"
> name="story.category" value="${actionBean.healthCategory}"/>
> <stripes:radio checked="${actionBean.story.category}"
> name="story.category" value="${actionBean.healthCategory}"/>
> I believe the reason for this is because the checked field in the
> InputRadioButtonTag.class is declared as a 'String checked' field. The
> checked attribute in the InputCheckboxTag.class on the other hand uses an
> 'Object checked' field. In the InputRadioButtonTag, the checked field is
> stored as the toString value of the object, instead of calling the object's
> custom converter, so the checked value never matches the value provided in
> the tag.
