validationValue called when displaying the form

[steph643]

Unless I missed something, the validationValue function is called on elements when:

• the form is displayed
• a validationEvent occurs

So in the doc:

// This is an optional method that lets you hook into the validation event

should be more:

// This is an optional method that lets you hook into the validation process, which occurs at form startup and upon a validation event

My second remark is that I need to distinguish between the startup call and the other ones. The reason is that I perform async validation and I don't want this to occur at startup time, because it takes time and I am sure my initial data is correct.

Did you think about that? Are you sure validating at startup is required? If it is, maybe there could be a template argument saying "please don't validate at startup"? Or a validationValue boolean argument saying "this call is the startup call"?

While we discuss this, can you think of a workaround to detect the startup call inside validationValue?

I definitely support getting rid of the validation on startup, in most cases it is just a burden. We can support this behavior more elegantly with a method on the form block to validate containing elements that can run be manually on startup (or whenever else we need to validate).
