Hi,
I have an Item with can have properties, which also can have properties.
I tried to get them in an elegant way recursively, but it does not work, but i don't want to use a service, since i will need this scenario quite often. It seems i overlooked a concept.
NAIVE Approach:
aql: self.properties + self.properties.subProperties + self.properties.subProperties.subProperties + self.properties.subProperties.subProperties.subProperties ....
How can i implement this?
Thanks,
Laurens

Hello Laurens,
Why don't you want to use a Java service?
In which case do you want to do it? Is it in a mapping definition?
Maybe the solution is provided by Sirius and not by AQL. So, to give you the best answer, I need to know your need and in which case Sirius you should use this.
Thanks.
Regards,

Hello,
I think that in your metaclass, you should add an EOperation getAllProperties. In its implementation you have a recursive method that look for properties, sub-properties etc. This way in your odesign, you will just need to call "aql: self.getAllProperties".
