Wappler 7 beta 27 - Server Side Formatter picker window not opening

[AdrianoLuiz]

Hi everyone,

After the latest Wappler update, I noticed an issue when trying to add a new formatter.

Steps to reproduce:

When I go to Server Data Bindings and click the (Add New Formatter) button, the formatter picker window doesn’t open — nothing happens. It used to open the list of formatters as expected.

Tested on:

• macOS
• Wappler version 7.0.0-b27
• Restarted Wappler
• Cleared cache
• Created a new project

Screenshot attached to show the exact moment where the issue occurs.

Anyone else experiencing this? Any workaround or rollback suggestions?

Thanks in advance!

Yes, this is a critical one and not only server side...

I’m currently in the middle of an important project, and it’s delivery week — this issue is blocking part of my workflow.

Is there any way to roll back to a previous stable version of Wappler?

I really need a quick solution to keep the project on track.

Thanks again for any help!

You can try for previous version:
https://account5.wappler.io/download/beta/Wappler-Mac-7.0.0-beta.26.dmg (Intel Chip)

https://account5.wappler.io/download/beta/Wappler-Mac-arm64-7.0.0-beta.26.dmg (Apple Silicon)

Or change 26 to the one you had and works as expected..

PS: Remember this is a Beta version and maybe you should rely on the stable version until beta ends to avoid things like this..

Found the problem. Will be fixed in the next beta that we will release asap

Fixed in Beta 28
