Hello all,

I am seeing weird thing in my project. I have a views having 2 custom properties linked to different databases. One of custom property gets deleted automatically and hence the script I have done throws “AttributeError” exception.

Why is this causing I have no idea. Please see snips for reference:

I have to add the property every time I open a view. I have done some scripting based on that data present in property called “Ascent” when the view opens. Please suggest.

Ignition Version: 8.1.1

Is there any script that writes to the `custom.Data` prop? If you add another prop into Data, does that also disappear?

Also, I like your design, very nice 🙂

Yes there is a query bind on `custom.Data` and the query has some parameters like Date. What I am doing is as soon as user lands on this page, setting the Date to now() which keeps the data updated.

I tried adding another prop it does not disappear, however I get _AttributeError_ right after I open the view in the designer.  
& Thanks man!
