I followed a tutorial which built some OpenCL code and included parameters in the bindings. Whenever the parameter values changed, the code automatically re-executed with the new values.

I was able to copy the code and got it working. But when I change a value, it does not update unless I first click in the view pane.

Even worse, once I wrap it as a HDA, it updates only for the first parameter change. After that I have close the project and reopen it to make another value change.

I assume there is a field somewhere to trigger atomatic re-execution Can someone guide me?

Thanks
