Appendix B. Known Bugs and Limitations
Applicability Rules & IS UNDEFINED

Event.Organiser IS UNDEFINED
Work Around
Refer to an attribute on the reference attribute instead
Event.Organiser.ID IS UNDEFINED
Arithmetic In Find
Problem/Limitation Description
Arithmetic operations with dates are not supported in FIND action, for example using the following will not work:
FIND Account WHERE Account.Date=CURRENT_DATE-1

FIND Account WHERE Account.Date= DATE_ADD(CURRENT_DATE,-1)
Functions Exclusive To Cloudbase Derby
Problem/Limitation Description

WORD_NUMBER
WORDS_FROM_LEFT

Work Around
None
Function Limitations In Subqueries
Problem/Limitation Description
MIN, MAX and AVG expressions are not supported if used in subqueries on groups. For example the following query is not supported if Transaction is a group:
FIND Account WHERE (COUNT Transaction WHERE (MAX.Transaction.Amount = 1000))
Work Around
Avoid using these expressions in subqueries
Loss Of LAN Connection
Problem/Limitation Description
If the Aware IM Server is started when either LAN or Internet connection is up and then either LAN goes down or Internet is disconnected, the server goes down too
Work Around
Start the Aware IM Server within the configuration that you intend to work with. For example, if you only use dial-up Internet connection occasionally make sure that you start the Aware IM Server first and then connect to the Internet. This way when you disconnect from the Internet Aware IM will continue to work properly.
MS Word Document Support In Linux & Mac

FIND Event WHERE NOT(LoggedInMember IN Event.Participants)
Work Around
In many cases the negated IN expression can be replaced by using the equivalent COUNT or EXISTS expression, for example:
FIND Event WHERE COUNT Member WHERE( Member IN Event.Participants AND Member=LoggedInMember) = 0

Required With Owned By References
Problem/Limitation Description
If two business objects are related through a parent/child relationship (see Reference Attributes) and the reference attribute to a child is defined as “Required” it is impossible to add a new child instance from a form of the parent instance using Add New button (see working_with_references_in_the_operation_mode)
Work Around
Do not force “Required” flag for reference attributes or create child instance first and then add it to a parent using Add button.
Sorting References In Business Object Group Queries
Problem/Limitation Description
Sorting on reference attributes in a query will not work if query searches business object group. For example, sorting in the following query will not work if Account is business object group:

Define a shortcut attribute and sort by it, for example:
FIND Account ORDER BY Account.OwnerName
Where OwnerName is the shortcut to Account.Owner.Name

FIND Client WHERE (COUNT Account WHERE (Account IN Client.Accounts)>3)
Work Around
Avoid using such constructs in queries
