Stefan,
Thanks for the explanation. Why I wanted to do this is because we have some free form fields in our templates that will be pre-filled with blank value when the PDF is rendered, but the user can type in anything later. Hence we created a set of dummy fields in the schema that the template designer could use to bind the free form fields, using a different field in the data connection each time. But since the number of templates is huge, there is a probability that the same dummy field is bound to a differnt text fields in multiple letters, by mistake. If this is the case and the end user chooses to stitch these two templates, then we have a problem.
Hence, our template designers wanted a solution that will relieve them of the responsibilty to keep track of the free form fields and their bindings.
Thanks,
Badri.
