Possible problem if key has no children but has own data

ewd-redis-globals/lib/apis/deleteNode.js

Lines 100 to 105 in 0cca19f

    
           if (redis.countZMembers.call(this, childrenKey) === 0) { 
        
             //console.log('no more children left for ' + childrenKey); 
        
             // no children left, so delete the node and recurse up a level 
        
             nodeKey = nodeRoot + this.key_separator + flatSubs; 
        
             //console.log('delete ' + nodeKey); 
        
             redis.deleteKey.call(this, nodeKey);

db.createNode('rob', ['a'], 'hello');
db.createNode('rob', ['a', 'b'], 'world');

db.deleteNode('rob', ['a', 'b']);

by using the same logic for ewd-memory-globals project I got the following

it seems it deletes node:rob:a but it shouldn't.

@robtweed WDYT?

	if (redis.countZMembers.call(this, childrenKey) === 0) {
	//console.log('no more children left for ' + childrenKey);
	// no children left, so delete the node and recurse up a level
	nodeKey = nodeRoot + this.key_separator + flatSubs;
	//console.log('delete ' + nodeKey);
	redis.deleteKey.call(this, nodeKey);
