Re: OGNL expertise please... complicated question
I'm not able to follow any of this. If you can give one small / clear example of what you are trying to do it would help me "help you".

Re: OGNL expertise please... complicated question
The user interface works and the back end works... The only thing that fails is that once the association is saved... it does not stick to the owner. This is due in part to the way trails saves it's models under the hood. To solve this I need to operate special rigging that sets/saves the association to the owner on the way out of the editor. inverse for both sides of the association is established at bootstrap time... pretty arcane... eh? We massage/alter the ejb3/hibernate annotations with a bootstrap interceptor and rig up our property descriptors. Guess I am definitely trails certified when I finish this one... - cheers Ken _ Like the way Microsoft Office Outlook works?

Re: OGNL expertise please... complicated question
Ok, here is a more actual runtime model...
Organization-<>---Director a hard OneToOne
Each is named in OGNL space as organization and director
Furthermore, each actual object has getter/setter
Organization.getDirector()
Director.getOrganization()
This is what I am receiving so far...
//Ognl.setValue("organization.director(#director)", model,
newAssociation)
//nosuchproperty
//Ognl.setValue("organization(#director)", model,
newAssociation)
//InnappropriateExpressionException
//Ognl.setValue("organization.director", model, newAssociation)
//nosuchproperty
//Ognl.setValue("organization", model, newAssociation)
//nosuchproperty
?
Any help is appreciated.
