I'm not sure "event" is the best name for your input. You might consider
changing it to <s:select name="currentProject"> or something.
Stripes will select the correct option based on the value of either a
request attribute named currentProject, if there is one, or the property
named currentProject in your SwitchProjectActionBean. But it will only do
the latter if there is an instance of SwitchProjectActionBean in your
request. I don't often suggest using s:useActionBean, but in this case it's
the simplest way to go. So you'll instantiate your SwitchProjectActionBean
using s:useActionBean, make sure its getCurrentProject() method always
returns the current project, and Stripes will select the option based on
that.
-- In your JSP
<s:useActionBean var="switchProjectActionBean"
beanclass="blah.action.SwitchEventActionBean" />
<s:form beanclass="blah.action.SwitchEventActionBean">
<s:select name="currentProject">
<s:options-collection
collection="${switchProjectActionBean.currentUser.projects}"
label="name" />
</s:select>
<s:submit name="switch" value="switch" />
</s:form>
-- In your SwitchProjectActionBean
public Project getCurrentProject() {
return getCurrentUser().getCurrentProject(); // or however you do it
}
That should do the trick. No promises, though :)

PS: It's worth noting that if you do, indeed, get and set the current
project using User.getCurrentProject() and User.setCurrentProject() then you
can name your s:select currentUser.currentProject and just have a
getter/setter for currentUser on your ActionBean.
