hi all,

I had a short query about a problem. I'am using hibernate 2.1 and xdoclet 1.2. And all goes fine. I define an one-many and become a stack overflow wenn i want to access from the child the parent.

example:

Parent:
Collection getChild();

Child:
Parent getChild();

when I call parent.getChild(); all goes fine but when I call child.getParent() I become the stackoverflow exception.

I think the problem that hibernate calls intern:

getChildren -> getParent -> getChildren -> getParent and so one?

how to deal with this problem?

XDoclet definition:

Child:


/**
* @hibernate.many-to-one cascade = "none" column = "`bin_id`" * @return
*/
public Bin getBin() {
return bin;
}


Parent:

/**
* @hibernate.set lazy="true" cascade = "none"
* @hibernate.collection-one-to-many
* @hibernate.collection-key column = "`bin_id`"
*/
public Collection getAnotatedSpectra() {
return anotatedSpectra;
}


whats my mistake? And this feature is realy importent!

bye and many thanks

is nobody here who can help me with this problem?

inverse="true"

thanks, i test this this afternoon

sorry, but at whitch point must i set inverse = true?

Read the documentation, "Parent/Child Relationship".

what do you think? im reading the manual and the xdoclet part is a little bit to small, i also read xdoclet in action and it does not help.

the inverse parameter is descriped at chater 6.2, 6.4 and 14.1.3 and there is no explanation

ups,

sorry i read the fat manual

I was talking about that too, but since the "Parent/Child Relationship" chapter didn't help you, suggested a search.

ok I read the parts and test this but i become an stack overflow exception again. But all files look good...

I can't see any failures and wonder why I ever become a stack overflow exception when I acces the paren object (Bin) from the child (spectra)
