Kasper Sørensen commented on METAMODEL-233:
-------------------------------------------
I've been trying to recreate it with this code:
{code}
// see METAMODEL-233
public void testCloneComplexQuery() throws Exception {
MutableTable table = new MutableTable("table");
Column recordTypeColumn = new MutableColumn("record_type", table);
Column changesetIdColumn = new MutableColumn("changeset_id", table);
Column datasourceNameColumn = new MutableColumn("datasource_name",
table);
table.addColumn(recordTypeColumn).addColumn(changesetIdColumn).addColumn(datasourceNameColumn);
Query query = new Query();
FromItem fromItem = new FromItem(table);
query.selectDistinct().select(new SelectItem(recordTypeColumn,
fromItem)).from(fromItem).where(new SelectItem(
changesetIdColumn, fromItem), OperatorType.EQUALS_TO, new
QueryParameter()).where(datasourceNameColumn,
OperatorType.EQUALS_TO, new QueryParameter());
query.clone();
}
{code}
but have not been successful... Are you sure this is the query that causes it?
I'm asking because I see the ArrayIndexOutOfBoundsException fails on trying to
retrieve the second element (index 1) from a FromItem list of size 1. And the
query quite clearly only has 1 FromItem ... Obviously that's the issue, but I
can't figure out how more than 1 FromItem can be there in the original query
before cloning it.
