Hello again,
I am having a couple of issues moving from 3.7 to 3.8.
First, I am getting an error when I make too many changes to a form (it seems to be especially when --maybe always-- after opening a new form in a sub window). The error says "you are not authorized to complete this action or access this resource", but if I hit the refresh button and then re-enter the fields it works after a second attempt. So for example in the screenshot below, I have added a PH check using a pop up window form from the list above, and then after adding additional data to the fields below, it gives the error in the picture. After refreshing (not with the browser but with the button in REI3), I can then add the data to the other fields and it lets me save as usual.
Second, I have different form where a state hides fields unless another field has a certain value, which is the default value for that particular field in the form. Thus those particular fields are supposed to be shown by default, but then vanish if the user changes the value of the first field. That worked well in 3.7, but now those fields are coming hidden, and if I delete and re-enter the same item in the first field (not needing to save, just deleting and immediately re-entering) only then do those fields become visable.
