Databinding workflow data to a user interface layer

In a workflow system data is exchanged using databinding constructs between the workflow and user interface layer. During an execution of a workflow a user interface instance is activated in anticipation of a user input event. The workflow is suspended and data for populating the user interface instance is provided to the user interface layer using a databinding construct from the workflow. Upon receiving user input, another instance of the workflow is loaded and data associated with the user input provided from the user interface to the workflow employing a databinding construct such that the other instance of the workflow is executed with the data associated with the user input.
