Problem with TreeCache

[damiano.pezzotti]

Hi,

I have a problem with Infinispan TreeCache adapter.

I build a treeCache data using the following code

        final Node rootNode = treeCache.getRoot();

        rootNode.addChild( Fqn.fromElements( "a", "b1", "c11" ) ).put(  "n1", "v1"  );

        rootNode.addChild( Fqn.fromElements( "a", "b1", "c12" ) ).put(  "n11", "v11"  );

        rootNode.addChild( Fqn.fromElements( "a", "b2", "c21"  ) ).put( "n2", "v2" );

When I try to access "a" children, I expect to obtain b1 and b2, but executing the following code

        logger.info( treeCache.getNode( Fqn.fromString( "a/" ) ).getChildrenNames() );

I obtain only b1

If I access directly node b2, I can obtaing a ref on it.

        logger.info( treeCache.getNode( Fqn.fromString( "a/b2" ) ));

          --> NodeImpl{fqn=/a/b2}

Is it a bug?

Thanks

Same problem if I use

        treeCache.put( Fqn.fromString( "/a/b1/c11" ), "n_c", "v_c" );

One more step.

if I remove from my cache configuration the expiration

        <expiration lifespan="60000" maxIdle="20000"/>

The problem doesn't occur.

Any idea?

That's pretty odd. Mind creating a jira in https://issues.jboss.org/browse/ISPN ? We'd also appreciate if you provide some test cases. These are easy to build now thanks to new Infinispan Maven Archetypes (http://community.jboss.org/docs/DOC-16201), see "Writing a test case for Infinispan" section.

Hi Damiano,

Thanks for the post. I was having the same issue and removing the the expiration tag solved the issue.

Just wondering how you resolved the issue with eviction after removing this tag. Because the contents I leave in the cache remain until a user remembers to log out. But a lot of times users do not and in that case the contents in the cache do not get timed out.

If you have any ideas do let me know.

Hi Swati,

In my case I have a curtom eviction policy that have to remove entries basing on application events. Then I created a custom cachelistener that removes entries from cache.
