Subject: MDL-9506 Fixed a bug with the fetch method. This method should not be called statical... 
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=1d4b666828e73092c46e6ec7183d4cc1f02c875f;p=moodle.git

MDL-9506 Fixed a bug with the fetch method. This method should not be called statically when setting an internal object. For example, when the grade_category is calling its load_parent_category, it should not call grade_category::fetch, but new grade_category. Otherwise, the method assigns the new variables to the calling object.
