Great post !
Error validation seems to be an issue still.

On a parent.save (with errors in child) the parent.errors contains duplicate entries in a weird format
(and child objects errors are empty)
childItem[0][1].description don’t understand
childItem[1][2].description don’t understand
childItem[0].description Great
childItem[1].description Great

If I loop thru the child, I get errors in the child object (yeah) but still duplicate entries in the parent when I call save.

Any clues?

So far my complex solution would be to loop thru the children, highlight the errors BEFORE calling save. Once validate on all child items passes THEN call save.

Thanks Rob. it seems to be working fine now. I also had to fix my view – the select field to a proper name:
name=”productItemList[${i}].product.id”

thanks

Very good article, thanks for sharing. I’m new to Grails, so if anyone can help me, I’d really appreciate. I’m trying to extend this example by associating Phone with a third domain called “product”.
so, in my phone domain I have a line for:
static belongsTo = [contact: Contact, product:Product]

In my Product domain:
static hasMany =[phones: Phone]

In my phone view:

When I try to save, I get an error message:
Property [product] of class [class com.easyinvt.Phone] cannot be null

It seems that Grails is not automatically mapping my product id to the Phone class.
Note: I’m using Grails 2.0

Thank you for the help
Paulo

I’am using Grails 2.0 and it throws the follwong exception in the save action:
null id in test.TargetEvaluation entry (don’t flush the Session after an exception occurs)
org.hibernate.AssertionFailure: null id in ….

It works fine in 1.3.7. And the data sent is the same. Has anyone the same issue?
Looks like the cascade does not work…

Never mind.
I forgot the closing tag of a div in the code, and it was all messed up.

hey guys.

I was wondering if you could help me.
I am doing the same thing with grails 2.0.0.RC1 and on IE works fine, but in Firefox or Chrome the values never reach the server. From what i saw in the source of the generated HTML , the new components aren’t added to the DOM in Firefox/Chrome.
Any hints on how to resolve this ?
Thanx.

Thanks for this useful post.

I was trying to run this application on Grails 2.0.0.RC1. I was able to create contact and phones with no problem. I was also be able to update a contact with NO phones, then add phones.

However, when I tried to update a contact with existing phones, I got “Not a collection, array, or map: cannot resolve nested value types. Stacktrace follows:” exception at line: contactInstance.properties = params.

I am wondering if anyone else have this problem?
