Changes
/* 2.6.4 */
* User Rights can be applied for Selective Items now. The rights evaluation happens during the assembling of the MetaDefintiions. If the current user does not have the right to see one Selective Item, it is removed from the Metadefinitions. If a SelectiveList does not have one single visible item, the entire list and all its references to it are removed.
* A new method (EvaluateBaseChildrenCollectionExt) on the UBIK ViewItems gives access to the current UBIK Session which provides a full set of new possibilities when customizing the children collection depending on (e.g.) the current login.
* UBIK provides a Numeric [[Sequence_Generator|Sequence Generator]] now. It gives the possibility to create unique sequential ids for different number groups.
