ValidationErrorReportResolution error with XHTML
------------------------------------------------
Key: STS-780
URL: http://www.stripesframework.org/jira/browse/STS-780
Project: Stripes
Issue Type: Bug
Components: Context Management
Affects Versions: Release 1.5.3
Reporter: Samuel Santos
When you click on a link that causes a validation error, and don't have a
sourcePage parameter in the query string, you'll get the nasty error returned
on the ActionBeanContext#getSourcePageResolution method line 228.
The problem is that ValidationErrorReportResolution writes directly to the
HttpServletResponse writer.
If you use a decoration framework like SiteMesh, you end up with malformed HTML
(e.g. two <html> tag elements).
That along may not be that severe as long as you don't use XHTML and its
draconian error handling, which will immediately cause your site to break.
Since mobile best practices dictate that mobile web applications should always
use the content-type application/xhtml+xml, we need to implement our own
ActionBeanContext and override the method getSourcePageResolution in each new
mobile application we develop:
@Override
public Resolution getSourcePageResolution() {
if (getSourcePage() == null) {
throw new IllegalStateException("Here's how it is. Someone (quite
possibly the Stripes Dispatcher) needed "
+ "to get the source page resolution. But no source page was
supplied in the "
+ "request, and unless you override
ActionBeanContext.getSourcePageResolution() "
+ "you're going to need that value. When you use a
<stripes:form> tag a hidden " + "field called '"
+ StripesConstants.URL_KEY_SOURCE_PAGE + "' is included. "
+ "If you write your own forms or links that could generate
validation errors, "
+ "you must include a value for this parameter. This can be
done by calling "
+ "request.getServletPath().");
} else {
return new ForwardResolution(getSourcePage());
}
}
This really needs to be fixed in order to fully support XHTML.
