Can you please provide OML file?


I faced this but this was not Bug, It was due to not refreshing correct carousel. and my filter was not correct there.

Please check these things in your application as well.

Hi Cynthia,

I have never experienced this before, but just for another alternative, you use a local variable as 'ItemsToShow' , use this variable inside carousel setting and then whenever you are changing something, you can assign ItemsToShow variable with value 4 on OnParameterChanged Event of web block.

You can try with this once. Thanks :)

Hi  Cynthia,

Please check the scope of the variable that you are using for the carousel. Check if it is related to any button click event and in that the updated data is not available for the carousel.

If you could attach the oml that will be helpful
