Does it only happen when validate method is called? Have you tried to force
a conversion error?
Have you mapped the stripes filter to JSPs, or are you using the
DynamicMappingFilter?
<filter-mapping>
<filter-name>StripesFilter</filter-name>
<url-pattern>*.jsp</url-pattern>
<dispatcher>REQUEST</dispatcher>
</filter-mapping>
The only thing I can think of is that the LayoutDefinitionTag is using some
uninitialized field

Asunto: [Stripes-users] Problems with @ValidationMethod
Hi,
I have a custom validation method like this:
@ValidationMethod(on={"save","saveAndExit"})
public void validate(ValidationErrors errors)
{
...
if ( ... error found ...) {
SimpleError error = new SimpleError("Error detected...");
errors.addGlobalError(error);
}
}
If there is any error at all, the program will throw a NullPointerException.
I am using stripes 1.5.1. With Stripes 1.5 I don't get the
NullPointerException, but the <stripes:errors/> won't show any error. The
stack trace as follows.
What did I do wrong?
Thanks
Yee
