Validate Error Visible
To check the input I use Edit Validate rule.
When entering erroneous data error does not appear.
I set up an Action Set, in which, by changing the value (Event - Change), I use Action "Post value", an error appears, but if I click on the field and remove the cursor from it (without changing the field value, the error disappears from the user's form (in the clipboard displayed)
How to make it so that the error is always displayed?
