Issue
After installing a Fix Pack, some forms or views are blank during runtime but are unaffected when opened in Designer. Forms may spin while loading but eventually initialize and a blank screen appears.
Example:
Resolution
A previous bug allowed K2 forms/views with their visibilities set to 'False' to actually be visible during runtime. Some users may have inadvertently un-checked 'Visible' from the General options in Designer and the setting went unnoticed until the bug was patched. Ensure that 'Visible' is selected for that form/view under the General options in K2 Designer.
In case you have multiple forms with this issue, you can easily identify all forms with 'Visible' property set to False using the below script:
SELECT [Name] ,[DisplayName] ,[Properties] FROM [Form].[Form] WHERE cast(Properties as varchar(max)) like '%IsVisible</Name>%<Value>false%' AND CreatedBy <> 'K2SQL:System'
