[hibernate-issues] [Hibernate-JIRA] Commented: (HBX-922) Error performing HQL completion when 'tab' characters are present

Joseph Marques commented on HBX-922:
------------------------------------

It also happens for nested queries.

This auto-completion works:

SELECT a
FROM ObjectA AS a
WHERE a.stuff = 
(SELECT s FROM ObjectS AS s JOIN s. <-- auto-completion here succeeds

But it fails when there's a tab before the nested query:

SELECT a
FROM ObjectA AS a
WHERE a.stuff = 
<tab>(SELECT s FROM ObjectS AS s JOIN s. <-- auto-completion here fails

> I'll get auto-completion for the "others" alias if I type:
> SELECT a 
> FROM ObjectA AS a 
> JOIN a.others AS others
> WHERE others.
> However, I if put a tab just before the join:
> SELECT a 
> FROM ObjectA AS a  
> <tab>JOIN a.others AS others
> WHERE others.
> Then I'll get an exception in the Error log:
> java.lang.StringIndexOutOfBoundsException: String index out of range: 108
