Hi,

You need to add parameter to exclude method on which you dont want to apply interceptor

for example at the very first run I used populate method to populate my page

<interceptor-ref name="token">
<param name="excludeMethods">populate</param>
</interceptor-ref>

if you have more than one method than you can use comma to separate methods

<interceptor-ref name="token">
<param name="excludeMethods">populate,add,save,anyothermethod</param>
</interceptor-ref>

Best Luck !
