Hi,
We have migrated a portal from SharePoint 2013 to SharePoint 2016. Nintex 2013 Forms (2.9.2.20) and Workflows (3.4.0.0) Standard have been used in the portal. In SharePoint 2016 we have version 4.5.1.0 Standard.
After the migration, users were getting an error while opening a form associated with a custom list. They are not able to create a new item, edit /view existing items. The form is working fine in SharePoint 2013 environment. In 2016 environment, they are getting the following error:
"An unexpected error has occurred.
Web Parts Maintenance Page: If you have permission, you can use this page to temporarily close Web Parts or remove personal settings. For more information, contact your site administrator."
In log file, we are getting following error:
"System.ArgumentException: Requested value 'Compatible' was not found. at System.Enum.TryParseEnum(Type enumType, String value, Boolean ignoreCase, EnumResult& parseResult) at System.Enum.Parse(Type enumType, String value, Boolean ignoreCase) at Nintex.Forms.SharePoint.FormControls.MultiLineTextBoxFormControl.ApplyDefaultFormProperties(FormControlProperties properties, FormVariable variable) at Nintex.Forms.Form.RefreshFormControls(IList`1 formVariableGroups) at Nintex.Forms.SharePoint.ListHelper.RefreshFormControls(Form form, SPContentType contentType) at Nintex.Workflow.Forms.ControlTemplates.ListForm.InitialiseFormFiller(String formXml, FormData data, Boolean hasEnterpriseLicense) at Nintex.Workflow.Forms.ControlTemplates.ListForm.InitialiseForm(Boolean hasEnterpriseLicense) at Nintex.Workflow.Forms.ControlTemplates.ListForm.OnInit(EventArgs e) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContaine) at System.Web.UI.Control.AddedControl(Control control, Int32 index) at Microsoft.SharePoint.WebPartPages.ListFormWebPart.CreateChildControls() at System.Web.UI.Control.EnsureChildControls() at Microsoft.SharePoint.WebPartPages.WebPart.get_WebPartMenu() at Microsoft.SharePoint.WebPartPages.ListFormWebPart.CreateWebPartMenu() at Microsoft.SharePoint.WebPartPages.WebPart.OnWebPartMenuCreate(Object sender, EventArgs s) at System.Web.UI.Control.OnLoad(EventArgs e) at Microsoft.SharePoint.WebPartPages.ListFormWebPart.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) "
When we try to open the Nintex form in desgin more, we get the following error in a dialog and no form is displayed:
"<head>
<title>Request Error</title>
<style>BODY ...... </style>
</head>
<body>
<div id="content">
<p class="heading1">Request Error</p>
<p>The server encountered an error processing the request. The exception message is 'Requested value 'Compatible' was not found.'. See server logs for more details. The exception stack trace is: </p>
<p> at System.Enum.TryParseEnum(Type enumType, String value, Boolean ignoreCase, EnumResult& parseResult)
at System.Enum.Parse(Type enumType, String value, Boolean ignoreCase)
at Nintex.Forms.SharePoint.FormControls.MultiLineTextBoxFormControl.ApplyDefaultFormP…"
We exported the form in 2013 environment and opened it in notepad, found one entry, not sure if it is related "<d2p1:RichTextMode>compatible</d2p1:RichTextMode>".
Kindly let me know what is the issue and how it can be fixed
Urgent response will be highly appreciated,
Thanks,
