Parameters

funName

Type: SystemString
The function name to invoke

argv

Type: RW.Server.ComponentMvValue
The arguments passed to the function funName

duplexFunName

Type: SystemString
The duplex global function name

duplexArgv

Type: RW.Server.ComponentMvValue
The duplex global function arguments

resultIndex (Optional)

Type: SystemInt32
The result of the funName function will be put at the resultIndex position in the array of arguments to the duplex function

inTrans (Optional)

Type: SystemBoolean
this parameter indicates if the callback must be executed using the transaction mechanism or not (see Transaction control in MvComponent). If equal to true and if no current transaction has been initialized, a new one is implicitly created and commited.
