14. A technical process for troubleshooting an application program executing in a computing environment, the technical process comprising the steps of: locating a transient expression in a markup; storing in a digital memory a copy of the transient expression prior to evaluating the transient expression; commencing execution of the full application program by at least one processor in the computing environment; evaluating the transient expression of the markup to support execution of the application program, thereby replacing the located transient expression by an evaluated expression; inspecting within a software tool at least one property of at least one visual construct which is defined by the markup; modifying a visual construct property, which may be the property of the inspecting step and in other cases may be a different property, thereby creating a property modification without pausing execution of the application program; and displaying the stored transient expression within the software tool, thereby providing information about the markup during execution of the application program even though the information is not presently available in the executing application program.
