In the Curve Descriptive Parameter View, the message "Cannot compute parameters. No node selected." does not appear when opening the view without any 4D data in the Data Manager. When a 4D dataset is loaded into the Data Manager it is auto-selected by the input field of the Curve Descriptive Parameter View. When the dataset is deleted again from the Data Manager the message "Cannot compute parameters. No node selected." is displayed. This is confusing for the user since it is not consistently displayed when the input field is empty.
In my opinion the message is not required at all, especially since with the new data selection concept the message "Please select time series" is shown in the input field, which is self explanatory and makes the "Cannot compute parameters. No node selected." message redundant.
