What's New in K2 Cloud Update 16

This topic describes new features, improvements, behavioral changes and known issues for Update 16 released in October 2021.

Considerations

The Style Profile Designer is not available in Internet Explorer (IE), as it uses CSS custom properties (CSS variables) which is not compatible with Internet Explorer. We suggest you use a modern browser for the Designer, such as Google Chrome.
Microsoft is deprecating the Azure Active Directory Graph API that K2 integrates with and is replacing it with Microsoft Graph API. To ensure continued integration K2 has made changes to Admin pre-consent to allow Microsoft Graph resource permissions before upgrading. The AAD Service instance and the SharePoint Online integration will also be updated. Operations support will work with you to ensure migration from AAD to MS Graph is complete in your environment. For more information see KB003673.
Download the enhanced Package and Deployment tool from https://<runtimeurl>/Management/Remote. Once downloaded, log a ticket with Nintex Customer Central to provide your public IP address ranges to K2 Operations. This allows access to your K2 Cloud environment from your network. Please see the Package and Deployment Considerations topic for further considerations about working with the Package and Deployment tool.
If you are using K2 for SharePoint, you must run through the K2 for SharePoint registration wizard after upgrade. See the following steps:
1. Click the K2 for SharePoint app from the Site Contents page or Quick Launch menu of the app catalog site and run through the Registration Wizard by clicking the Registration Wizard link in the Administration section to register the app with your K2 environment's URL. (If you do not see the Registration wizard, make sure you are on the app catalog).
2. Deploy the app to one or more site collections using the Manage App Deployments page in SharePoint. A link to this page is provided on the K2 for SharePoint settings page. It is recommended you do this by paths rather than individual URLs, but individual URLs give you more control regarding which site collections have K2 integration. You should deploy as a SharePoint Administrator if you are deploying to multiple site collections.

Fix Packs

The following Fix Packs apply to this version of K2 Cloud. To determine the version and Fix Packs applied to your environment, please see the KB article KB003537: How to determine the installed K2 software version, Cumulative Updates, and Fix Packs for K2 Platform and K2 Cloud

Fix Pack	Release Date	Details
Fix Pack 18	June 2022	If a workflow has multiple Create Reference or SmartObject steps linked to the same SmartObject, the SmartObject name contains a full stop, and you rename the default generated output mapping, a duplicate reference was created in the Object Browser. In K2 Mobile, when opening a workflow task from Workspace and the task contains a form with a File Attachment control, the control did not allow files to be attached. When using the data of a Create Reference step in a workflow to populate the "To" field of a Send Email step, a "The email address 'System.String[]', is invalid" error occurred. When trying to open a view or a form in K2 for SharePoint for the first time, the view or form would load, then request authentication and load again.

Follow the steps below to successfully apply the fix: Redeploy the workflow containing the "Start when any Workflow Errors" start event.
Fix Pack 17	May 2022	When adding HTML to the Rich Text control containing a custom font that is not included in the Rich Text control, generating a PDF converted the text into an unreadable format. When adding a Drop-Down List control to a list toolbar and using a style profile, the control was added to its own row in the toolbar and not aligned in the same manner as the rest of the controls. When you have a workflow with a SmartObject containing a SmartObject method that returns a file or document, a "The SmartObject contains a property mapping that references a removed SmartObject property" error occurred when trying to deploy the workflow. When using the PDF Converter service in a workflow, an “unable to connect to the K2 PDF Converter Service” error occurred.

Fix Pack 15	April 2022	When you have more than one SmartObject in a category and you try to drag a SmartObject from the Toolbox > SmartObjects > [Category] folder in the workflow designer onto the canvas, the last SmartObject in the list displayed instead of the one you dragged onto the canvas. When you have a column of Decimal or Number data type which has an expression returning a value of number or decimal in an Editable list view and you try to sort at runtime, the column did not sort correctly.
Fix Pack 14	April 2022	When using the Worklist control and removing the default "Status not equals Sleep" filter at runtime, tasks of other users were visible.
Fix Pack 13	March 2022	When using hyperlinks or URLs containing spaces in a form, the links did not work when trying to access it. When using the SharePoint Get List Item by View method or "First" list option in a SmartObject to filter results, the filters did not apply. Follow the steps below to successfully apply the fix: In Management > Integration > Services Instances, edit the affected SharePoint service instance and click OK without changing anything. Click Edit again to see the new service key called Include View Item Limit in the Service Keys section. Type “true” next to the service key and click OK. Ensure you do this for all affected SharePoint services instances. When using a split step in a workflow and selecting the custom logic option, multiple paths could not be selected for the configuration.
