I'm working on a time card form for my company and they want me to have the form calculate the dates for the two week pay period when the ending day of the pay period is selected, that part I have down through code. The problem I am running into though is that when the user is using Adobe reader to digitally sign and send the file to their supervisor the file is changing the selection date field back to the first selection in the drop down list after the first digital signature is applied and the file saved. This error does not occur when the user is utilizing Adobe Pro though. Does anyone have any ideas? I'm wondering if it is something to do with the dropdown list settings or some kind of locking feature not working properly with the reader version. I am editing/creating the form through LiveCycle Designer ES4.
