An active path designer tool allows users to combine graphical workflow editing and data binding in a web based framework. The tool may be built on top of a web based extensible client framework (XTCF) to allow a client's information technology (IT) personnel to graphically design activities. A folder based display of available nuggets allows users to drag and drop nuggets onto a canvas. The users can then establish connections between nuggets by graphically drawing an edge between nuggets. The edges thus provide a flow of work for the activity. In addition, users can specify data bindings to be transferred between nuggets by means of input and output pop-up menus on each nugget. An input menu may contain a list of data available for input to a nugget, while an output menu may contain a list of data available for output. A user may draw a line between input and output menu entries to bind an output of one nugget to an input of another nugget. In addition, an underlying XTCF platform allows a graphic display of the nuggets to be generated based on independently stored data and formatting information, which may be freely manipulated by a user.
