-----------------------------------

             Summary: Configuration parser doesn't allow to have <async/>, <properties/> and <singleton/> elements inside of <store/> element
                 Key: ISPN-4349
                 URL: https://issues.jboss.org/browse/ISPN-4349
             Project: Infinispan
          Issue Type: Bug
          Components: Configuration, Loaders and Stores
    Affects Versions: 6.0.2.Final
            Reporter: Alexey Olenev
            Assignee: Dan Berindei


Despite infinispan-config-6.0.xsd says that there can be a <async/>, <properties/> and <singleton/> elements inside of <store/>, actually if you configure custom store using <store/> element, configuration parser (org.infinispan.configuration.parsing.Parser60) throws exception:

This exception occurs because of following code snippet from org.infinispan.configuration.parsing.Parser60 (lines 668-685):

if (store != null) {  
    if (store instanceof SingleFileStore) {  
        SingleFileStoreConfigurationBuilder sfs = builder.persistence().addSingleFileStore();  
        if (fetchPersistentState != null)  
           sfs.fetchPersistentState(fetchPersistentState);  
        if (ignoreModifications != null)  
           sfs.ignoreModifications(ignoreModifications);  
        if (purgeOnStartup != null)  
           sfs.purgeOnStartup(purgeOnStartup);  
        if (preload != null)  
           sfs.preload(preload);  
        if (shared != null)  
           sfs.shared(shared);  
        parseStoreChildren(reader, sfs);  
    } else if (store instanceof ClusterLoader) {  
        ClusterLoaderConfigurationBuilder cscb = builder.persistence().addClusterLoader();  
         parseLoaderChildren(reader, cscb);  
}

It means that method parseStoreChildren() will be called just if my custom store is a subclass of SingleFileStore, and this method is responsible for parsing such elements as <async/>, <properties/> and <singleton/>
