SM OR - fileUpload issue when executing a save(JSF ajax request) during upload

[shlomom]

the loading stays forever when an upload is interrupted by a save action. this is the javascript error we get:

singleFileUpload.js.jsf?ln=openfaces&ofver=3.1.EA1.612:330 Uncaught TypeError: Cannot set property 'progress' of null singleFileUpload.js.jsf?ln=openfaces&ofver=3.1.EA1.612:330(anonymous function) ajaxUtil.js.jsf?ln=openfaces&ofver=3.1.EA1.612:496(anonymous function) ajaxUtil.js.jsf?ln=openfaces&ofver=3.1.EA1.612:265runScriptWhenReady ajaxUtil.js.jsf?ln=openfaces&ofver=3.1.EA1.612:276window.OpenFaces.Ajax._runScript ajaxUtil.js.jsf?ln=openfaces&ofver=3.1.EA1.612:494processExtension ajaxUtil.js.jsf?ln=openfaces&ofver=3.1.EA1.612:528eventHandler jsf.js.jsf?ln=javax.faces:1sendEvent jsf.js.jsf?ln=javax.faces:1onComplete jsf.js.jsf?ln=javax.faces:1jsf.ajax.req.xmlReq.onreadystatechange
