First I changed a line in the function createBean() in my flowscript the former line was:
bean = parser.parseDocument(is).getDocumentElement(); now, there is bean = parser.parseDocument(is); to obtain the full XML document. I added /root in <fb:context/>. My binding file is now: <?xml version="1.0"?> <fb:context xmlns:fb="http://apache.org/cocoon/forms/1.0#binding"; xmlns:fd="http://apache.org/cocoon/forms/1.0#definition"; path="/root"> <fb:value id="number" path="beannumber"> <fd:convertor datatype="long"/> </fb:value> </fb:context> My data file is: <?xml version="1.0"?> <root> <beannumber>5</beannumber> </root> The form.load(bean) is pretty good, but I don't know how to get the value of the bean after form.save(bean). bean.getElementsByTagName("beannumber") returns a DeepNodeList-Object. I get an object Node() via the method item() of the class DeepNodeListImpl. var number = bean.getElementsByTagName("beannumber"); var tmp = number.item(0); tmp is now an object of type Node(). When I say tmp.getNodeName() I get "beannumber". (that's correct) When I say tmp.getNodeValue I get "null". How can I receive the value of my bean?
