Within the application management cycle, there are 2 procedures that require input parameters from the user. Input parameters are required when deploying a web application on the domain as well as when reconfiguring the deployed application. To let the user enter parameters via GUI, it is necessary to create parameter input forms and put them to the /forms folder of the installation package.
The parameter input procedure can require a single form or a multipage GUI. At a transfer from one form to another, the old form 'dies' and the values entered by the user need to be saved first. This is done by means of a special 'close form' event handler that reads all parameter values from the fields of the form and saves them in memory. Thus, each form requires a matching handler file. The matching handler files are added to the /forms folder beside their forms.
