Problem of

[jreeman]

I have a problem when updating a cache node with a data.

I do something like this :

node = cachegetRoot().addChild(fqn);
 node.put(key, value);

That throws a NodeNotValidException (at the "node.put(key, value);" line) :

UnversionedNode (INVALID!)
org.jboss.cache.NodeNotValidException: Node /sections is not valid. Perhaps it has been moved or removed.

Could you tell me in wich case such a problem occurs because I do nothing really specific ?

When disabling the eviction policy :

<!-- Policy configurations : FIFO Policy -->
<attribute name="EvictionPolicyConfig">
<config>
<attribute name="policyClass">org.jboss.cache.eviction.FIFOPolicy</attribute>
<attribute name="maxNodes">1000</attribute>
</config>
</attribute>

There is no more exception, but I'm afraid that the cache size will grow indefinitely.

Could you give me some piece of advice about these issue ?

Thx

I added regions and _default_ in the xml configuration file and it seems now better.
