Issue After an upgrade to EBO version 3 the  "Alarm State Sort Order" in EBO Webstation is not following the  "Alarm State Sort Order" set in Workstation for certain Alarm Views. Workstation:   Webstation: Product Line EcoStruxure Building Operation Environment Building Operation Webstation version 3.0 and later Cause This issue is only seen on Alarm views upgraded from a version earlier than 1.9 to EBO 3.0 or later The problem is that in EBO version 1.9 Webstation did not follow the sort order for Workstation, back then the sort order in the alarm view in Workstation and Webstation was separated.

Issue Vista Workstation crashes when the content of a column in any View (Alarms, Events, Search Results etc.) exceeds 259 characters. Environment Vista 5.1.7 Cause In the unlikely event that the content of a column in a Vista View exceeds a limit of 259 characters, Vista Workstation crashes and must be restarted.  Vista Server is not affected. The problem was discovered while doing a search for TGML graphics, with the property "Bindings" selected.  The search returns one graphic on each row and all the bindings for that graphic are displayed in the property column on that row.  Resolution Upgrade to Vista 5.1.8, when available.  The issue is fixed by truncating the contents of any View column to 259 characters. The issue is highly unlikely to occur in normal use.  In the case of the Bindings search, the workaround is to use the "Change Reference" tool instead
