I'm trying to add a custom property as boolean, but architect always add a '' inside code.
Ex.: Adding a property called fullscreen with value true result as fullscreen: 'true' while I want fullscreen: true
This annoyed me in ExtDesigner before, but I don't think it has been fixed in Architect as the properties are still stored in JSON.
You could probably solve this with an override, though this will get tedious if you have a lot of fields like this. In my case I ran into problems with checkboxes having the inputValue "true" and unchecked value "false" submitting their value as strings rather than booleans. My solution was to fix the data prior to submit, though this is by no means the final answer.
