Well, apologies, but I don't know how to repro this issue. Can you send us a small console app & database (minimal, preferably just one table) that does so?]]> Wed, 16 Jun 2010 13:44:08 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=1896&PID=7339#7339 Random Validation Issue : Regardless of how validation is... http://www.ideablade.com/forum/forum_posts.asp?TID=1896&PID=7334#7334 Author: orcities

Regardless of how validation is being performed. The data is valid. And it is throwing a generic error that I can not track. It is a DevForce error.
 
Every value in the PM DataSet is valid. They all pass validation but fail on save.

Instance and OnPostSet, applied to a particular verifier, means that verifier will be run after a set of the triggering property (OnPostSet), and also when instance validation is ordered (Instance). But you still have to order instance validation explicitly (unlike triggered validation); and it seems to be instance validation that is at issue here. What is ordering the instance validation? (It is not DevForce!)

Code doesn't change spontaneously, so the only thing that could account for that would be that the data was somehow put into an invalid state, so that a test that was passed yesterday is not being passed today.

Suppose an invalid value were introduced outside your app (so that no triggered validation occurred at the time the value was changed). This still wouldn't cause Devforce to reject the save unless you order successful instance validation as a condition for the save. Of course, the back-end database could still reject the save it it contained data that broke *it's* rules.

1. No change. User was usinging it successfully one day then the next it wouldn't work.

2. Triggered Validation. Instance and OnPostSet
 
3. I have looked at all entities in the dataset being saved. No entity should fail validation. The specific entity that is failing, at the time, has valid data.

After what change did this start happening?

When the user modifies one specific entity and tries to save a "Save failed - Entity Validation Failure(s)" error is thrown.
The problem is that it doesn't say which entity. I have checked the entire PersistenceManager.DataSet to see if I could find the issue and I cannot.


What is causing the validation to be run? DevForce Classic doesn't perform validation on a save unless your code asks it to.

You have access to the collection of entities being saved in the PersistenceManager's Saving event. Normally that's where people perform instance validation in DFClassic.]]> Tue, 15 Jun 2010 16:05:46 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=1896&PID=7325#7325 Random Validation Issue : My product has been live for quite... http://www.ideablade.com/forum/forum_posts.asp?TID=1896&PID=7318#7318 Author: orcities

My product has been live for quite some time. I am now getting an error thrown on validation, which I doubt it actually is. When the user modifies one specific entity and tries to save a "Save failed - Entity Validation Failure(s)" error is thrown.

I have tried looking for the entities in the PM with the rowstate of modified and looking at it's properties and there is no issue. I have validated that entity by forcing validation to see if it returns the validation error and it does not. But, on save after this entity has been modified there is an error.
 
SaveResult:
Failed - Normal Error: Save failed - Entity Validation Failure(s)
