Hello,

We are working on a pharo issue 7284: "Error: cannot remove non empty category".

A simple script to reproduce this issue is the following.

Gofer new

� squeaksource: 'Roassal';�

package: 'ConfigurationOfRoassal';

load.

((Smalltalk at: #ConfigurationOfRoassal) project version: '1.200') load.

((Smalltalk at: #ConfigurationOfRoassal) project version: '1.269') load.

The problem is in the method MCOrganizationDefinition>>unload, it uses the removeCategory: method and this method don't delete the classes inside the category and raise an error:�

� � MCOrganizationDefinition>>unload

� � categories do: [ :c | SystemOrganization removeCategory:c ].

A possible solution for this could be use the removeSystemCategory: instead, since it delete the classes inside and then the category.

� � MCOrganizationDefinition>>unload

� � categories do: [ :c | SystemOrganization removeSystemCategory: c ].

Perhaps, we are not sure about our solution. We want to have your opinion about it :)

It's removing the classes inside the category is what we really want to do? There is a reason for not deleting the classes inside?

Regards,

Juan Pablo & Alejandro
