I also don't use <jsp:useBean />, but in this case, I would use
<stripes:useActionBean /> within a JSP tag file:
[optionsComponent.tag]
<stripes:useActionBean
var="componentListBean"
beanclass="ComponentListActionBean" />
<stripes:options-collection
collection="${componentListBean.allComponents}"
label="name" value="id"/>
You will have to create the new ComponentListActionBean, but this
saves you from defining the 'allComponent' property and its getter
in every action bean that needs to display the drop-down list.
And in any JSP in the webapp, you can use the tag without modifying
the main action bean:
<stripes:select name="bug.component.id">
<tags:optionsComponent />
</stripes:select>
--
Actually, there is no advantage of using <stripes:useActionBean />
over <jsp:useBean /> in the above example, but
<stripes:useActionBean /> allows you to
1) access session attributes or context resources in its logic.
2) reuse the same action bean for returning the same list in various
formats (json, xml, etc.) quite easily.
--
Another option is to use <jsp:include /> in the tag file, but it
will cause performance loss in the bulk edit page.
