Hi everybody,
I have a problem with the TreeGenerator - a Cocoon Generator contained into the
hippo-cocoon-extensions - which performs a DASL query and render the results
maintaining the hierarchical structure of the repository; it's very handy to
render Website sitemaps.
The problem is that when I use it I get a NPE:
Caused by: java.lang.NullPointerException
at
org.apache.cocoon.components.store.impl.EventAwareTransientStore.get(EventAwareTransientStore.java:143)
at
nl.hippo.cocoon.generation.repository.navigation.RepositoryNode.fetchChildNodes(RepositoryNode.java:77)
at
nl.hippo.cocoon.generation.repository.navigation.RepositoryNode.<init>(RepositoryNode.java:47)
at
nl.hippo.cocoon.generation.repository.navigation.TreeGenerator.generate(TreeGenerator.java:89)
at
org.apache.cocoon.components.pipeline.impl.ExpiresCachingProcessingPipeline.processXMLPipeline(ExpiresCachingProcessingPipeline.java:138)
... 41 more
Hereby is the configuration I use in my sitemap:
<map:generator label="content" logger="sitemap.generator.file"
name="tree" pool-grow="4" pool-max="32" pool-min="4"
src="nl.hippo.cocoon.generation.repository.navigation.TreeGenerator">
<!--<exclude-documents>false</exclude-documents>-->
<properties default-namespace="http://hippo.nl/cms/1.0"; display="element">
<prop><name>caption</name></prop>
<prop><name>index</name></prop>
<prop><name>type</name></prop>
<prop><name>displayname</name><namespace>DAV:</namespace></prop>
</properties>
<orderby>index</orderby>
</map:generator>
<map:generate type="tree" >
<map:parameter name="startpath" value="{repository:files}"/>
<map:parameter name="path" value="content/nl/producten"/>
<map:parameter name="depth" value="2"/>
</map:generate>
Any ideas?
TIA
Met vriendelijke groet,
