Hibernate: org.hibernate.AssertionFailure: null id don't flush the Session after an exception occurs

[Peter Petrov]

Does anybody know what the Hibernate stack trace below means (some details & fix tips)?
I found a few sources on the web but not too explanatory, I think.
Some references or links would also be appreciated about this issue and its cause.

I mean I just would like to understand and fix the issue below.

Also, seems to me the id field is annotated property in the ReportEntry entity class.

   

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "ReportEntryID")
    private Integer reportEntryID;

But if so - what is the problem then?

Any help would be appreciated.
Many thanks in advance.

[Jaikiran Pai]

From my understanding, this is just a side effect of the real exception that has occured some lines above this stacktrace. Do you see any additional stacktrace before this? If not, is your code catching some exception but not logging or rethrowing it back?

Jaikiran,
I do have same problem and I see following error before the error show above. Any idea about the problem. This used to work till yesterday.

Dec 29, 2009 12:03:27 AM org.hibernate.AssertionFailure <init>
SEVERE: an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session)
org.hibernate.AssertionFailure: null id in com.desiweb.locals.bo.BuySellRent entry (don't flush the Session after an exception occurs)
   

[Jignesh Patel]

You are right Jaikiran,
The problem was not in id of hibernate entity.

I have following code in my hibernate entity

  	@Pattern(regex="[0-9]+",message="#{messages['buysellrent.phoneNum.numeric']}")
	@Column(name = "PHONE_NUM", length = 12)
	public String getPhoneNum() {
		return this.phoneNum;
	}

	public void setPhoneNum(String phoneNum) {
		this.phoneNum = phoneNum;
	}  

Following code in my seam facelet

   				<div class="entry">
				<div class="label"><h:outputLabel for="phoneNum">Phone Number:</h:outputLabel>
				</div>
				<div class="input"><s:decorate id="phoneNumDecorate">
					<h:inputText id="phoneNum" value="#{buysellrent.phoneNum}" maxlength="12">
					<a:support event="onblur" reRender="phoneNumDecorate" />	
					</h:inputText>				
				</s:decorate></div>
				</div> 

Somehow my front was sending phoneNum ="" so whenever hibernate validation fails and drove me crazy, by showing

null id error

.
Unfortunately hibernate never sent appropriate error message. I figured out problem only when I went into debug mode.
