[jira] [Updated] (VXQUERY-38) fn:substring off by one

["Preston Carman (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/VXQUERY-38?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Preston Carman updated VXQUERY-38:
----------------------------------

    Attachment: SubstringError1.patch

Found a few more issues with substring. 
1. Wrong parameters for the iterator.
2. Reset was not being called for the parent iterator.
3. Added a check for end of string to allow for early exiting of the function call, for parameters that don't match the string length.
4. (ticket) Substring is generated correctly.
