Issue:
Every time a user makes a selection to the first multi-select input control values, the input control resets (scrolls back) the selection focus to the start of the list and the user has to scroll down again to make additional selections. This happens only if there is a cascade where the second input control query has a connected parameter to the first input control. For example, when the second control query contains :
where $X{IN, customer_id, customer}
where 'customer' is a connected parameter to the first multi-select input control.
This issue does not occur when there are no cascading input controls.
This issue can be reproduced as follows :
1. Run a report containing an input control (first) and a cascading input control (second)
2. Make input control selections to the first input control and scroll down the first input control to make more selections
3. Observe that the first input control is scrolled back to the top of list for every selection made
Every time the Input Control refreshes and scrolls back to the top of values, users will need to scroll down the list again which makes usability awkward and difficult. It is expected that the Input Control selection maintains its focus position without having to re-scroll down every time.
Solution:
Every time a user makes a selection to the first input control values, these two internal http requests are made:
http://server:8080/jasperserver-pro/rest_v2/reports/public/Samples/Reports/AllAccounts/inputControls/customer;other/values?freshData=false&selectedOnly=true http://server:8080/jasperserver-pro/rest_v2/reports/public/Samples/Reports/AllAccounts/inputControls/customer;other/values/pagination?freshData=false&includeTotalCount=true
and because of these requests the input controls are refreshed and scrolled back to the top of the list.
Note: The sample report above is a modified version of the Accounts report to contain cascading input control.
