Bug 120216 Group dialog should be showed even dataset is not set.
- Add a table report item - do not set the data set - try creating a new table group. - An error is shown Expected behavior - As part of the template requirements, we dont want UI to do the validation. User should be able to go and define a group, even if the dataset is not defined.
