When two users open a changes at the same time, 'Cancel Change' Dialog shows for second user when first user cancels the changeDescriptionWhen two users open a change request at the same time, 'Cancel Change' Dialog shows for second user when first user cancels the changeSteps to Reproduce Navigate to an instance.Impersonate two users in two different browsers.Open the same change request as two users in two different browsers.As user1, click 'Cancel change' > Dialog opens > Type reason > Submit/OK.As user2, verify that the 'Cancel change' dialog opens.WorkaroundIf the client script "Show Cancel Reason modal" has been customised It's imperative that those customisations are understood and why they're needed since this workaround will REPLACE the the script of this Client Script.Export the client script to XML to preserve the customisation Import the attached client script "sys_script_client_aa78ab09c313101035ae3f52c1d3ae20.xml" Note: if customisations where made, this workaround does not take them into account other than preserving them by exporting them XMLRelated Problem: PRB1530021
