Is this a bug or on purpose? If you have a tool cached and you move it into or out of a container, the cache clears.
You have to remember the Container is also a Tool, so when you modify any tool that is cached then Alteryx has clear the cache.
@JohnMaty I have confirmed the same thing. I built an Input with a select tool. Ran it, then right clicked and added select tool to container and it indeed got rid of the cache. I also re-cached the workflow and then right clicked and deleted the container only and it got rid of the cache.
At Inspire this year, I showed it to our presenter and they seemed shocked this happened. Thats why I thought this was a bug.
