Hiya, no the ajax does not trigger the preparation of the web block!

Can you share the module?

Hi Kilian, I can't unfortunately as it is a company project.

I feared as much, but without a module it's difficult to determine what goes wrong. Just to be sure, in the OnNotify you Ajax Refresh the Web Block itself? Or an outer Container?

Yes sorry about that! I'm refreshing the WB itself. But I did also try with the outer container and this also didn't work. 

Here's an example module that shows it working, both with a button and with a notify.

Hi Chris,

I'm not using Events (maybe this is the problem).

No, events are for signalling from the Web Block to the Screen, not the other way around.

Thanks for confirming, I thought this was the case!

Thanks for clarifying Kilian. I misunderstood the thought of the question.

Hi Asha,

I think you should review the values if they are properly passed to the Web Block.

Check as well if you are using the correctly referencing the values of the Input parameters or there might some aggregate in the preparation of the web block or local variables in it that you have accidentally used in lieu of such.

Thank you and kind regards,

Chris
