We have a recurring problem with users forgetting to create a grouping for group assignments.
Sometimes they create the groups afterwards, or rather completely forget to do so, and sometimes they select the wrong grouping setting, under Common Module Settings.
The settings are especially a source of trouble when they create more groups later in the course and the students are members of more than one group.
- If no grouping is created in the course, the choice Students submit in groups under the section Group Submission Settings should be disabled, with an explaining text: "To create a Group assignment you must first create a grouping and groups for the assignment."
- If a grouping is created in the course, the choice Students submit in groups under the section_ Group Submission Settings_ is enabled and a grouping can be selected. The selection of a grouping should be mandatory, and if the user tries to save the group assignment before having specified a grouping this is rejected, with an explanation that a grouping must be selected for the assignment.
