Was the file reader extended or signed?
We are using reader extensions on the form to allow file saves.
We have done some further testing and discovered a couple of important things:
1) If we open a version of the form that has grown (even after several saves via the browser), but open it in Adobe Reader then save it, the form reverts to its original size. So, whatever the plug-in is adding to file on a save is being removed again if Adobe Reader is used.
2) This is not just happening on the form mentioned above. It appears to happen on any form in which we have embedded XML data. We have another multi-page form which uses a pure XML interface (i.e., no bound fields from SAP), and it grows in the same fashion when saved via the browser. The original form had the bound table, but within the table one field of each row contains a large XML string which is used to dynamically populate the form pages as the user navigates.
When we ran the test on simple SAP-bound form with no embedded XML, the form size does not change when it is saved via the browser. This suggests that my mention of the dynamic table in the original form is of no consequence in the behavior (except perhaps that it happens to be where we store the embedded XML data).
