More experimentation shows that the "white space" problem shows up whenever I try to use XmlWriter.WriteNode(XPathNavigator,bool) passing in an XPathNavigator for a node that has a field which has not been assigned a value. <br />Is this by design or is this a bug?<br />https://www.infopathdev.com:443/forums/thread/6170.aspxWed, 04 Apr 2007 22:42:23 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:6170MylesRip0https://www.infopathdev.com:443/forums/thread/6170.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=6170Hi,<br /><br />I have code in a browser-enabled form that clones a node to create a new sibling and then overwrites several values on the new node. On one of the fields I got the error, “Schema validation found non-data type errors.” I found a blog from the InfoPath team saying that the error could be caused by a nillable field. (Here is the link in case you are interested:<a target="_blank" href=http://blogs.msdn.com/infopath/archive/2006/11/28/the-xsi-nil-attribute.aspx>http://blogs.msdn.com/infopath/archive/2006/11/28/the-xsi-nil-attribute.aspx</a> ) As per the blog entry, I added code to remove the nil attribute. <br /><br />Unfortunately, this caused another problem. If I then try to clone the new node to create another sibling, I get the error, "Only white space characters should be used." This error only happens if you try to make a copy of a node that had the nil attribute removed from one of its member elements. <br /><br />Here is an excerpt from the code where the "white space" error shows up. <br /><br />XmlWriter writer = lastChangeOrder.InsertAfter();<br />writer.WriteNode(lastChangeOrder, true); // &lt;-- Error happens here.<br />writer.Close();<br />lastChangeOrder.MoveToNext();<br /><br />Any ideas? Thanks!<br />
