One file creates an item option named 'user_group' under the 'AWS account request' catalog item, which is a is a Lookup select box that references the sys_user_group table and its reference qualifier is 'javascript: 'manager=' + current.variables.user'. Another file creates an item option named 'user' under the 'AWS account request' catalog item, which is a Lookup select box that references the sys_user table. The next file is a catalog script for the 'AWS account request' catalog item, which logs the value of the user_group field when there is a change to the User field. | 1. Load the XML files.Notice that these XML files create a item options named 'user_group' and 'user' under the 'AWS account request' catalog item, and that Lookup select boxes are created. 2. Navigate to the catalog item. 3. Change the User field to any value. {#zurich-patch-11-hf-4-PO__ol_q5z_31g_fkc} Expected behavior: The User Group field should be cleared, and the alert should show an empty value. Actual behavior: The User Group field is cleared in the UI, but the alert shows the previous value. | [ ] {#zurich-patch-11-hf-4-PO__all-other-fixes} ## Fixes included {#zurich-patch-11-hf-4-PO__section_u5y_gzf_fkc} Unless any exceptions are noted, you can safely upgrade to this release version from any of the versions listed below.
