WorkFlow Builder

- doGet() - Form gets rendered to the browser
- Click on "Insert Step" button {Function called "FILE_steps_loadSteps(e, wfId,app)"}
- Steps text boxes with 'step title' & 'approver email', 'Insert' button, Text 'Insert after step' with text box for step say "0" is rendered to browser
- In Steps - "Insert after step" is set as "0" and when 'Insert' button is clicked
- Dialog Box error states "Error encountered: Incompatible type passed in as parameter"
