I have made a wf5 which give back undefined for $form.state.FilepIcker.value is undefined. according to Mobile Viewer the value not undefined and the wf craches because it thinks a file is added. The same is with sum statistics. In mobile the value is undefined in sandbox I got a real number. How can these differences be explained!

  Hi Erik,

   

  If your workflow is checking for the existence of files, you could use =$form1.state.filePicker1.value.files.length instead, which will return 0 when no files have been added.

   

  The Sandbox uses our Typescript workflow implementation while the Mobile Viewer uses our .NET implementation, so there are differences between the two, but I will file an issue for this as they should handle this case equivalently.

   

  Thanks, Stefan
