I'm experiencing a strange bug in 1.2.0, on an eager loaded one to many relationship. The first time I run the code, openJPA retrieves the parent entity and eager fetches the CORRECT child entities. The second time around, it fetches the parent entity and fetches the INCORRECT child entities (specifically, it fetches the child entities of the parent entity in the previous query).
Here's the SQL to illustrate: First run: SELECT t0.AMDCTL_ID, t0.VRS_NBR, t0.AMDSEQ_CDE, t0.DPLORD_NBR, t0.FND_CDE, t0.RSL_DTE FROM EBSTATUS.TBL_AMDCTL t0 WHERE t0.FND_CDE = ? [params=(String) 0000001] SELECT t0.AMDCTL_ID, t1.AMDDES_ID, t1.VRS_NBR, t1.AMD_DES, t1.AMDCTL_ID, t1.EFC_DTE FROM EBSTATUS.TBL_AMDCTL t0 INNER JOIN EBSTATUS.TBL_AMDDES t1 ON t0.AMDCTL_ID = t1.AMDCTL_ID WHERE t0.FND_CDE = ? ORDER BY t0.AMDCTL_ID ASC [params=(String) 0000001] Second run: SELECT t0.AMDCTL_ID, t0.VRS_NBR, t0.AMDSEQ_CDE, t0.DPLORD_NBR, t0.FND_CDE, t0.RSL_DTE FROM EBSTATUS.TBL_AMDCTL t0 WHERE t0.FND_CDE = ? [params=(String) 0001001] SELECT t0.AMDCTL_ID, t1.AMDDES_ID, t1.VRS_NBR, t1.AMD_DES, t1.AMDCTL_ID, t1.EFC_DTE FROM EBSTATUS.TBL_AMDCTL t0 INNER JOIN EBSTATUS.TBL_AMDDES t1 ON t0.AMDCTL_ID = t1.AMDCTL_ID WHERE t0.FND_CDE = ? ORDER BY t0.AMDCTL_ID ASC [params=(String) 0000001] Somehow its caching the second query, even though I've turned off the DataCache and QueryCache. I've had to revert back to OpenJPA 1.1.0. Here's my mappings: TblAmdctl.java @OneToMany(mappedBy="tblAmdctl",fetch = FetchType.EAGER,cascade = { CascadeType.PERSIST,CascadeType.MERGE}) private Collection<TblAmddes> tblAmddess = new ArrayList<TblAmddes>(); TblAmddes.java @ManyToOne(fetch = FetchType.LAZY,cascade = { CascadeType.PERSIST,CascadeType.MERGE }) @JoinColumns([EMAIL PROTECTED](name = "AMDCTL_ID",referencedColumnName="AMDCTL_ID")}) @ForeignKey private TblAmdctl tblAmdctl; -- View this message in context: http://n2.nabble.com/OpenJPA-1.2.0-Bug-on-FetchType.EAGER-tp1100274p1100274.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
