Tank you for your explanation.
I tried to use com.ibm.xsp.model.DataSource as type. On the page where I use my custom control and try to set this property I got oly the seletction xp:dominoDocument or xp:domnoView.
If I select xp:dominoDocument I get the hole set of properties, which are also available with the normal definition of the data source, like action, allowDeletedDocuments, computeDocument and so on. On which property do I have to set the formula for the doc handle?
