Now experience the joy of freeing yourself from the time consuming process of handling the form submission sequence for custom forms. Canvas has extended the request modeler submission capabilities to custom forms by enabling you to map the Request Model ID to the custom forms in Form Designer.

You can wire the actions in custom forms and/or custom containers to the request modeler actions and choose to launch the custom forms in multiple ways such as with or without the container using any of the following APIs:
- canvas.launch()
- getWindowByFormObj()
- getWindowByFormId()
