The following comment has been added to this issue:
Author: Tim Schafer
Created: Thu, 4 Sep 2003 12:18 PM
Body:
Adding the following change
if(str.length() == 0)
return new Character( ' ' );
else
return new Character( str.charAt(0) );
in place of
return new Character( str.charAt(0) );
makes the problem go away
The part I don't understand is why CharacterType was even
being used
The column in the mysql 4.0.13 database is of type varchar(15)

The following comment has been added to this issue:
Author: Tim Schafer
Created: Thu, 4 Sep 2003 5:48 PM
Body:
Ok the reason that CharacterType is being used is that the
class being mapped to uses a char for that attribute
Duh!
I created a String attribute in the class to map to and all is well
But there does seems to be a bug here
I created a char column in the database
copied the varchar column to it
and mapped that to the char attribute
If that char column is blank it will trip up the same section
of CharacterType
Mapping a char column from a mysql table to a char attribute
does seem a legitimate use case.
And hibernate shouldn't blow up because that char column is blank
I'm not sure if the blank char should map to a null char
or a ' '
But I think ' ' would preserve the semantics in the case of Mysql
columns
whereas null would imply the column was NULL in the database
This bug's priority can be lowered as far as I'm concerned though

Author: the_Ellessar
Created: Thu, 16 Oct 2003 6:30 AM
Body:
I came across the same problem using SAPDB 7.4. I think it should either return null or a character. But what happens now is that I get a java.lang.StringIndexOutOfBoundsException. It is now not possible to use character type's if a value in the database can be null.
Fix:
