I try to use Mustang and development version of NetBeans 4.2, but I can't open any project; when I try to select it or open it in 'Open Project' dialog, I receive exception org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces. Unfortunately I'm not sure if this is problem of NetBeans or Mustang. SuSE Linux 9.3 (i586) NetBeans version 200508161800 Java version 1.6.0-ea-b47 org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces. at com.sun.org.apache.xerces.internal.dom.AttrNSImpl.setName(AttrNSImpl.java:146) at com.sun.org.apache.xerces.internal.dom.AttrNSImpl.<init>(AttrNSImpl.java:115) at com.sun.org.apache.xerces.internal.dom.CoreDocumentImpl.createAttributeNS(CoreDocumentImpl.java:2109) at com.sun.org.apache.xerces.internal.dom.CoreDocumentImpl.importNode(CoreDocumentImpl.java:1622) at com.sun.org.apache.xerces.internal.dom.CoreDocumentImpl.importNode(CoreDocumentImpl.java:1586) at com.sun.org.apache.xerces.internal.dom.CoreDocumentImpl.importNode(CoreDocumentImpl.java:1528) at org.netbeans.spi.project.support.ant.AntProjectHelper.cloneSafely(AntProjectHelper.java:824)
