Hi,
I followed the tutorial at :
http://www.wdogsystems.com/opencms/opencms/demos/structured_content_editing.html
but it seems there is a problem. When i create a new File using the
structured content, an exception occured :
java.lang.NullPointerException at
org.opencms.xml.content.CmsXmlContent.getContentDefinition(CmsXmlContent.java:625)
at org.opencms.xml.content.CmsXmlContent.<init>(CmsXmlContent.java:127)
...
Here is my opencms-modules.xml :
...
<resourcetypes>
<type
class="org.opencms.file.type.CmsResourceTypeXmlContent" name="DemoType"
id="7001">
<param
name="schema">/system/modules/mymodule/schemas/sample_article.xsd</param>
</type>
</resourcetypes>
<explorertypes>
<explorertype name="DemoType" key="fileicon.DemoType"
icon="xmlcontent.gif" reference="xmlcontent">
<newresource page="structurecontent"
uri="newresource_xmlcontent.jsp?newresourcetype=DemoType" order="7001" />
<accesscontrol>
<accessentry principal="GROUP.Administrators"
permissions="+r+v+w+c"/>
<accessentry principal="GROUP.Projectmanagers"
permissions="+r+v+w+c"/>
<accessentry principal="GROUP.Users"
permissions="+r+v+w+c"/>
</accesscontrol>
</explorertype>
</explorertypes>
...
And here my /system/modules/mymodule/schemas/sample_article.xsd :
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<xsd:include schemaLocation="opencms://opencms-xmlcontent.xsd" />
<xsd:element name="DemoTypes"
type="OpenCmsDemoTypes" />
<xsd:complexType name="OpenCmsDemoTypes">
<xsd:sequence>
<xsd:element name="DemoType"
type="OpenCmsDemoType" minOccurs="0"
maxOccurs="unbounded" />
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="OpenCmsDemoType">
<xsd:sequence>
<xsd:element name="Title" type="OpenCmsString" />
<xsd:element name="Teaser" type="OpenCmsString"
maxOccurs="3" />
<xsd:element name="Text" type="OpenCmsHtml" />
</xsd:sequence>
<xsd:attribute name="language" type="OpenCmsLocale"
use="required" />
</xsd:complexType>
</xsd:schema>
I tried to configure the workspace.properties in classes/mymodules/ (and
even adding the following lines in __property/workspace.properties...) :
fileicon.DemoType = Sample Systems Article
title.DemoType = Create a new Sample Systems Article
I really don't know what I do wrong... i have an OpenCMS 7.0.4 and all is
correct when i restart my server... no error in Tomcat logs...
help... please... lol
