Summary 0000073: Need a functionality so that any update can be raised when two people are trying to save data
Description As of now if two people are working on the same oberon object, there is highly possible that one person changes are overwritten by the second person.

if we have some logic such as counter, when the second person tries to save, the system should raise an exception if the person trying to save has a stale object. Mirko we already discussed this and I strongly feel that it should be handled in platform as the DB transactions are not exposed to application level

 Added the new "checkupdate" option for objects (in the lifecycle definition) and links (in the linktype definition)

lifecycle edit <LCNAME> ... [!|not]checkupdate... ;
lifecycle show <LCNAME> get { ... checkupdate ... } token ... ;

linktype edit <LTNAME> ... [!|not]checkupdate... ;
linktype show <LTNAME> get { ... checkupdate... } token ... ;

If the "checkupdate" flag is enabled, each modification performed on the object/link increases an internal counter. When another user updates the instance, the sync counter that you read before appling your changes is not the same and the platform blocks the operation returning the message like: "Your instance is out-of-date, please reload it before apply changes"

It is possible to read the current value of sync counter in the following way:

object show <id/CNR> get { ... counter ... } token ... ;
link show <id> get { ... counter ... } token ... ;

when you need to update the instance you may use the "sync" option, reporting the previously read value:

object edit <id/CNR> sync <value> ... ;
link edit <id> sync <value> ... ;

 Added also the new SDK methods for Lifecycle and LinkType classe:

void setCheckUpdate(boolean checkUpdate) // Set the checkUpdate option
boolean isCheckUpdate() // Check if the checkUpdate option is active

and the getter method: int getSyncCounter()

to read the current sync counter for ObjectObj and Link classes instances
