Philip Breau added a comment - 24/Jul/13 10:27 AM js error under same conditions is also occurring in the ICEfaces 1.8 Showcase: <script type= "text/javascript" > var submit = function() { if (arguments.length == 1 && arguments[0] == 1) { parent.Ice.InputFileIdPostUpload = 'iceform:icepnltabset:0:myInputFile_inputFile'; parent.Ice.InputFileIdPreUpload = null ; } else { return ; } try { if (parent.document.getElementById('iceform')) { parent.document.getElementById('iceform').submit(); } } catch (e) { parent.logger.warn('Form not available', e); } finally { parent.Ice.InputFileIdPreUpload = null ; parent.Ice.InputFileIdPostUpload = null ; } }; document.getElementsByTagName('form')[0].onsubmit = submit; var uploadEnd = function() { submit(1);}; if (window.attachEvent) { window.attachEvent('onunload', uploadEnd); } else { window.onunload = uploadEnd; } </script> 'parent.Ice' on the first reference of InputFileIdPostUpload is undefined. Looks like the script from the file upload iframe is running on a navigation and the reference to parent.Ice has already been unloaded.

Mark Collette added a comment - 24/Jul/13 12:17 PM And where does that script come from, that Philip posted?

Philip Breau added a comment - 24/Jul/13 12:19 PM - edited It's rendered by the Input File component. InputFile.java

Mark Collette added a comment - 24/Jul/13 12:47 PM It makes sense now, the ice:inputFile has postUpload set to true and preUpload set to false, and this is the script that gets rendered. So all I need is the DOM updates that come back in the upload, to see if that's nuking the iframe, and thus ruining the postUpload environment.

Mark Collette added a comment - 24/Jul/13 1:05 PM I'm investigating using onbeforeunload instead of onunload, or using a setTimeout in the postUpload handling, in case the parent is temporarily unavailable.

Mircea Toma added a comment - 25/Jul/13 4:42 PM The fix applied modifies the iframes included in the element that is about to be updated to force the browser into honouring the 'beforeunload' and 'unload' events. Modified InputFile iframe to use 'beforeunload' event so that the elements it works with are still available.
