Hi Hilmar,

Using IDX indexes (create with INDEX ON ... TO somefile.idx) is unneeded you can use structural indexes (created with INDEX ON ... TAG someTag) which are automaticly released when the view is released.

Using IDX indexes also give problems (errors) when involved with transactions. CDX indexes do not suffer from this limitation.

Walter,
