I have an app with several pages. I would like to put the property "data-dom-cache"="true" on one of the pages.
Problem:
I do that (set the attibute),
I properly save both the properties and the project,
then close the page or close the entire editor
then I reopen the page and go to more properties...
...any my property is gone!
(very strange)
Any hints?
I found the issue, and it might help people in the forum:
You can set page properties, but if your page is based on a template, they disappear. If you break apart the template, it works.
Maybe something to document or improve in future appery releases 
Hello Chris,
This is how it works, please read more about Page templates here https://devcenter.appery.io/documenta...
