XML overriding column names for ArrayList attributes causes exception.
----------------------------------------------------------------------
Key: OPENJPA-1957
URL: https://issues.apache.org/jira/browse/OPENJPA-1957
Project: OpenJPA
Issue Type: Bug
Components: jdbc
Affects Versions: 2.1.0, 2.0.1, 1.2.2
Reporter: Heath Thomann
Assignee: Heath Thomann
Priority: Minor
Take an entity class similar to the following:
public class MyEntity implements Serializable {
protected String _id;
protected ArrayList<String> myStrings = new ArrayList<String>();
.......
and a corresponding XML mapping in orm.xml:
<entity class="somepackage.MyEntity" access="FIELD">
<table name="MY_TABLE"/>
<attributes>
<id name="_id">
<column name="MYENTITY_ID" nullable="false" />
</id>
<basic name="myStrings">
<column name="MY_STRINGS"/>
<lob/>
</basic>
</attributes>
</entity>
With this configuration, the following exception can occur:
org.apache.openjpa.persistence.ArgumentException: You have supplied columns for
"somepackage.MyEntity.myStrings<element:class java.lang.String>", but this
mapping cannot have columns in this context.
