Workaround for simple chart not working on Chrome, Safari & Internet Explorer
When you want to show the simple chart widget in the same data view where you want to display some attributes all works fine on Firefox. I found strange behaviour however on Chrome, Safari & Internet Explorer: A data constraint based on the current object will not work at all. An empty form is shown with only the labels and the title of the graph. A data constraint based on the current user will show the graph but in the rest of the form only the labels are shown. A workaround for this is to position the simple chart outside the data view and to change your domain model and in such a way that you can use the currrent user in your data constraint. Not the prettiest solution but it works. If you know another solution without changing the domain model please let me know.
