Use ERXDirectActionBatchNavigationBar
<wo:ERXDirectActionBatchNavigationBar
actionName = "organizations"
containerCssClass = "paginator"
batchSize = "$dgOrganizations.batchCount"
currentBatchIndex = "$dgOrganizations.currentBatchIndex"
showPageNumbers = true
numberOfObjects = "$dgOrganizations.allObjects.@count"
/>
Please note that it will use Direct Actions, so it won't work with REST routes.
I'm planning to do a similar component for REST because I need it for
wocommunity.org, but I won't work on this before end of this month.
