Try to find a good set of steps that reproduce the problem&nbsp;and we&#39;ll investigate.https://www.infopathdev.com:443/forums/thread/69817.aspxTue, 30 Aug 2011 14:37:18 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:69817shniggens0https://www.infopathdev.com:443/forums/thread/69817.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=69817<p>I don&#39;t know when exactly this happens (maybe upon saving?), but my filter formulas (lots of them) lose their current() function at random times.&nbsp; It&#39;s really irritating to go through and re-enter the current() on multiple filters every now and then.&nbsp; </p>
