When I change a dataset of a list but the dataset I changed to does not have a paramater that I've set and mapped in the first dataset, JSS will throw a big ERROR when I open that file after closing.
JSS becomes UNUSABLE untill I fix it in iReport or an XML editor.
2 datasets. 1st with a paramater added. 2nd with no paramaters added.
1 list with 1st dataset. On the list hit the Paramaters button and map the Paramater of the 1st dataset to a value.
Change the dataset of the list to the 2nd.
Save file and Quit JSS
Open JSS -> Error.
