Hi Seam experts,

I have a common problem which I am not able to solve despite referring to some good references. Kindly let me know what went wrong. I am using seam 2.0.2CR1 with Oracle XE. Thanks in advance.

I have 2 simple tables with a parent-child relationships:-

CREATE TABLE "TEST" ( "TEST_ID" NUMBER(18,0), "TEST_NAME" VARCHAR2(50), CONSTRAINT "TEST_PK" PRIMARY KEY ("TEST_ID") ENABLE )

CREATE TABLE "TEST_ITEM" ( "TEST_ITEM_ID" NUMBER(18,0), "TEST_ITEM_NAME" VARCHAR2(50), "TEST_ID" NUMBER(18,0) NOT NULL ENABLE, CONSTRAINT "TEST_ITEM_PK" PRIMARY KEY ("TEST_ITEM_ID") ENABLE, CONSTRAINT "TEST_ITEM_CON" FOREIGN KEY ("TEST_ID") REFERENCES "TEST" ("TEST_ID") ON DELETE CASCADE ENABLE )

In the Test.java entity, I have the following declaration:-

@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "test") public Set<TestItem> getTestItems() { return this.testItems; }

In the TestItem.java entity, I have the following declaration:-

@ManyToOne(cascade = CascadeType.ALL, fetch = FetchType.EAGER) @JoinColumn(name = "TEST_ID", nullable = false) @NotNull public Test getTest() { return this.test; }

In the TestHome.java entity home, I have the following code:-

@Override public String persist(){ Test test = getInstance(); TestItem item = new TestItem(); item.setTestItemName("testing"); item.setTest(test); test.getTestItems().add(item); return super.persist(); }

And finally, I am getting the following common error:-
