合并后DomainClass.getAll（）无法正常工作

Question

I was trying to update a row on the database and noticed that once the row was updated, getAll stopped working correctly. All the records that were updated, started missing from getAll's result.

for instance, imagine you have a list of products [product1, product2, product3]. if I do something like product2.someProperty = 2 followed by a product2.merge(), product two will start missing from the list. So the result of Products.getAll() will be [product1, product3].

(Sorry if this is a noob question)

If I perform a Product.get(idOfUpdatedProduct), it will work. I've checked the database and the merge is updating the data correctly. The problem seems to be on the GetAll() method. findAll() presents the same behavior.

my code:

---action
def update() {
        Product product = productService.detail(params.id?.toLong())
        bindData(product, params)
        productService.updateProduct(product)
        redirect action: "show", params: [id: params.id]
}

---service
void updateProduct(product) {

        product.validate()
        StringBuilder str = new StringBuilder()
        product.errors.allErrors.each { str << "${it}" }

        if (!str.toString().isEmpty()) throw new Exception("Error: ${str.toString()}")

        product.merge(flush: true, failOnError: true)

    }

Answer 1

I found the problem.

the result was actually being returned, but for some reason, it was placed in the middle of the list.

I solved it by sorting the list.
