Hi I had merged today a patch [1] that renames canDoAction to validate in CommandBase and all references Please note that canDo boolean flags where replaced with valid and canDoAction was replaced all over with validate/validation all over the code including javadoc, comments and logging messages. For example getCanDoActionMessages became getValidationMessages failCanDoAction became failValidation And so on .... [1] https://gerrit.ovirt.org/#/c/50632/ Thanks Eli Mesika
