Using Partial Property Update in Dash 2.9 for Handling Circular Callbacks

I’m really excited about the updates in Dash 2.9 and looking forward to applying them to my Dash app.

I have a question regarding the use of Partial Property Update in my callback. Does the Patch() function only work when there is a single callback output?

I’m dealing with Circular Callbacks to synchronize two components in my application. Any guidance on how to effectively utilize the Patch() function in this context would be greatly appreciated.

HI @wowwwn,

I’m not sure if I understand you correctly but take a look at the first example I shared here:

I use Patch() and allow_duplicate=True
