Union tool not showing data when kept inside a control container

Question

Hi,

I am getting this weird error where if I have a 2 or more inputs kept in a control container/ tool container and one of them is disabled and then these are connected to a union which is inside a control container I don't get any output from the union tool even though I have data in on the input tool kept in enabled container.

If I keep the union tool outside its working. Can anyone help me with this. I want the union tool to be inside the control container.

it is somewhat like this

were i want some other control container to be triggered after this container that has union. I can keep the union outside the container but just want to know why this error is coming up. because of this there's no data at union output anchor.

@MinhLO where can I report this bug?

I think this is the bug. One thing you can avoid is using the block until done tool if your data stream is not complicated. In this case, you can wait before the union tool. But I think union tool always wait before the process of incoming steam is done, so you may dont need control container or block until done tool

Hi @Dhrish

It looks extremely similar to a bug I raised to Alteryx a couple of months ago.

Weirdly enough there is also a bug with the number of tools that you put in control containers. If more than 1, then as you mention, no data is sent.

We decided in my company to change the design, every time we encountered this use case.
The most effective was by removing AMP / CC.

Also I would advise you to raise this as a bug, they might fix it in the next version :)
