[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-8558) SEAM Entity creator uses Integer for @Version - results in NullPointerException on update

[Peter Larsen (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-8558?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12596326#comment-12596326 ] 

Peter Larsen commented on JBIDE-8558:
-------------------------------------

Max - the schema was generated from the model - not the other way around. If you add @NotNull to Integer Version you get errors on insert because the value isn't present.  If you change the type to int, the column is initialized correct - and it works regardless of the column being null/not null (unless you specify @NotNull the column is created as NULLable).

> When creating entities from scratch, the "Create SEAM Entity" wizard will generate code with the the following:
> @Version
> private Integer version;
> This construct unfortunately results in new records being created with NULL in the version column. On subsequent updates this then results in NullPointerException.
> Changing Integer to int solves the problem.
