By default ‘list’ pages are generated to use the <paginate> tag, and this invokes the list action to retrieve the next set of results.
If you are using an action other than the default list action, include the action="" attribute on the tag to use an alternative action method:
<code><g:paginate action="${listType}" total="${Purchase.count()}" /></code>
In the above example the action method is the result of a value set from the previous action method to indicate which action method is to be used.
