[jira] [Commented] (TINKERPOP-763) IsStep broken when profiling is enabled.

["Marko A. Rodriguez (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TINKERPOP-763?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15094985#comment-15094985 ] 

Marko A. Rodriguez commented on TINKERPOP-763:
----------------------------------------------

This happens because the internal traversal never has {{next()}} called, only {{hasNext()}}, thus, it does NOT generate traversers.  As such, I don't know what to do. I don't want to {{next()}} cause that is a pointless computation. However, I think what it does is "right" ... the last {{IsStep}} did NOT produce traversers as its a "filter" and thus, 0 count and 0 traversers. It is doing what it says! I will close, if this is NOT cool, please reopen with recommendations.

> The .profile()-Step and the is()-Step do not play well together. Results are not emitted when profiling is enabled. 
> Perhaps this is the same type of issue that caused problems between the Profile and Where/Match steps???
