How to order module callbacks or how to prioritise modules

Amin_El-Assaad

Hi !

 

How can we prioritise a callback above another ?

Is there a way to no let modules step on each others' toe from a code level point of view? I dont want this to be a module or system wide setting, I just want a specific callback's logic to flow a certain way. Any example of an implementation of this sort ?

E.g. There is a foreign module that wants to make a legitimate action on an object, but another module's callback was actioned prior to it and changed the item's properties - which resulted in a server exception and non of the modules' goals were acheived !

Many thanks !

Hi Amin,

 

This may not work for all callbacks but will work for most. Typicallythe order in which the callbacks are executed is the order in which they are loadedby Content Server. On way to force the order is by orphaning the root object ofthe module that needs to be loaded first into the other. This needs knowledge ofthe builder and changing the existing module.

I know it is possible to influence the loading order inopentext.ini, but I never really investigated that.

 

Personally I would complain by the creators of both modules thatare implemented in a way that breaks other modules.
