When adding a task to a job the console gets an unhandled exception:
Unhandled error
Object reference not set to an instance of an object.
[System.NullReferenceException @ Altiris.TaskManagement.Web]
at Altiris.TaskManagement.Web.PreviewItemPicker.OnInit(EventArgs e)
at System.Web.UI.Control.InitRecursive(Control namingContainer)
at System.Web.UI.Page.ProcessRequestMain(Boolean
includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
ITMS 7.6 and later
The web picker files are corrupted.
Verify that the following files are updated to the correct version:
Altiris\TaskManagement\web\PreviewItemPicker.aspx
Altiris\TaskManagement\web\bin\Altiris.TaskMangement.Web.Dll
To fix this you may need to reinstall Task Management then clear the temporary .net files and restart IIS.
If that does not address the issue then contact support for the proper version of files for you installation.
