I use macros all the time, and I would love if the metadata could persist between runs no matter what tools exist in the macro. I've attached a simple example which should demonstrate the issue. After running the module once, the select tool (4) is populated with the expected data; however, as soon as anything changes (like a tool is dropped onto the canvas), the select tool (4) is no longer receiving the metadata to properly be populated. I've added the crosstab tool from the macro onto my workflow to demonstrate that it's only a problem when the tool is inside a macro. It makes it difficult at times to work with workflows that utilize macros due to the metadata constantly disappearing anytime a change is made. The solution would be for the metadata from the last run to persist until the next run. This is how the crosstab tool is working on my workflow, but putting it inside the macro changes its behavior.
