hi,I want create a new content type for press release. I'm studing from Alfresco Enterprise Content Management Implementation book that use Alfresco 1.4, but I use the 2.1 version of Alfresco.Add this line to /extension/customModel.xm file
<types>
<!– Definition of new Content Type: Press Release –>
<type name="custom:pressrelease">
<title>Press Release</title>
<parent>cm:content</parent>
<properties>
<property name="custom:PRName">
<title>PR Person Name</title>
<type>d:text</type>
</property>
<property name="custom:PREmail">
<title>PR Person Email</title>
<type>d:text</type>
</property>
<property name="custom:PRPhone">
<title>PR Person Phone</title>
<type>d:text</type>
</property>
<property name="custom:PRDate">
<title>PR Released Date</title>
<type>d:date</type>
</property>
</properties>
<mandatory-aspects>
<aspect>cm:versionable</aspect>
</mandatory-aspects>
</type>
</types>
Open the web-client-config-custom.xml file and add the following lines of code.<!– Lists the custom aspect in business rules Action wizard –>
<config evaluator="string-compare" condition="Action Wizards">
<aspects>
<aspect name="custom:CustomerDetails"/>
</aspects>
<subtypes>
<type name="custom:pressrelease"/>
</subtypes>
</config>
Add the following XML code just before the block shown above. This code ensures that the press release content type is listed when you create new content.
<config evaluator="string-compare" condition="Content Wizards">
<content-types>
<type name="custom:pressrelease" />
</content-types>
</config>
Add the following XML code just before the block shown above. This code ensures that the properties are available to edit in the edit properties window for press release content.
<config evaluator="node-type" condition="custom:pressrelease">
<property-sheet>
<show-property name="mimetype"
display-label-id="content_type"
component-generator="MimeTypeSelectorGenerator" />
<show-property name="size"
display-label-id="size"
converter="org.alfresco.faces.BByteSizeConverter"
show-in-edit-mode="false" />
<show-property name="custom:PRName" />
<show-property name="custom:PREmail" />
<show-property name="custom:PRPhone" />
<show-property name="custom:PRDate" />
</property-sheet>
</config>
After making these changes to the configuration files, restart Alfresco.The DOS shell of Alfresco gimme the following error:GRAVE: Error listenerStart
