grails hdiv integration - session succeeds but get HDIV_PARAMETER_NOT_EXISTS exception - spring

Question

I am trying to integrate hdiv in a grails 2.0.3 application.
I have made all the changes mentioned in the hdiv-reference doc for spring mvc in my grails application.
When the application starts up I can see that hdiv validatorfilter is initialized and Hdiv session is created.
Any help is appreciated

Answer 1

Per the installation documentation for HDIV maybe try this:
<filter-mapping>
<filter-name>ValidatorFilter</filter-name>
<!-- Grails dispatcher servlet -->
<servlet-name>grails</servlet-name>
</filter-mapping>
You might also need to add gsp servlet mapping but I would try with just grails front controller first.
<filter-mapping>
<filter-name>ValidatorFilter</filter-name>
<!-- Grails dispatcher servlet -->
<servlet-name>grails</servlet-name>
<!-- Groovy Server Pages servlet -->
<servlet-name>gsp</servlet-name>
</filter-mapping>
