Does Composer support OOTB attaching aspects automatically to new objects based on format?
-Mark
In Composer, when it comes to automatically attaching aspects to objects, we only support automatically attaching aspect to all instances of an object type. If you want to attach aspects automatically to certain instances of an object type, you'll have to write code to do it.
you can attach aspects by default in composer to all instances, but be careful, because aspects attached by default can´t deattach by code. I recommend you that use TBO to attach aspects when it´s possible(for example in doSave method), in otherwise, wdk.
In 6.5 SP1, we added a feature to the SysObject editor where you can attach an aspect to the SysObject you are installing.
