No, its not a runtime expression.
If you look at the code in FormTag you'll see that its not
results.append("\" action=\"");
results.append(response.encodeURL(RequestUtils.getActionMappingURL(action,
pageContext)));
results.append("\"");
It simply pulls the action mapping from the config.
I changed my code to
results.append("\" action=\"");
// check if we have a bean thats exposing a formaction property, if so, use that
property, otherwise use our assigned action value in the jsp page
try {
Object value = RequestUtils.lookup(pageContext, beanName,"formaction", null);
if (value != null && !value.toString().equals(""))
{
this.action=ResponseUtils.filter(value.toString());
System.out.println(value.toString());
}
} catch (Exception e)
{
e.printStackTrace();
}
results.append(response.encodeURL(RequestUtils.getActionMappingURL(action,
pageContext)));
