If you are using FormServer 7.1 you may want to disable client-side caching. This will prevent previously entered values from appearing on a new form when you open it in a fresh browser instance.
The problem is that Acrobat/Reader is caching the form (along with its data). It does this based on the URL address (same URL = same form/data). Unfortunately, since this is a client setting there is no easy way to disable it.
Here are some suggestions to achieve this:
1) on the form (i.e. will be on a form by form basis):
add this code into the form:ready event -
var oDoc = event.target; oDoc.nocache = true;
2) make the URL unique:
An easy way of doing this is to return a date/time stamp as an unused parameter in the URL. This can be easily added by either the JSP or the servlet. For example:
3) Also consider setting the cache control headers in your response:
// Set content to expire far in the past. response.setHeader("Expires", "Thu, 1 Jan 1970 12:00:00 GMT"); // Set standard HTTP/1.1 no-cache headers. response.setHeader("Cache-Control", "no-store, no-cache, must-revalidate"); // Set special IE extended HTTP/1.1 no-cache headers (use addHeader). response.addHeader("Cache-Control", "post-check=0, pre-check=0"); // Set standard HTTP/1.0 no-cache header. response.setHeader("Pragma", "no-cache");
