subWebVI limitations

bhpowell — Wed, 06 Oct 2021 18:43:26 GMT

I selected a portion of my webVI's diagram and created a subWebVI. I was trying to encapsulate some of the code which talks to my web service.

Apparently, you can't pass an HTTP client handle to a subWebVI...

Warning

HTTP Client Handle

You can only use this type of terminal on the diagram of a WebVI. Adding the control to the WebVI panel is not currently supported.

I'm just trying to clean up my code. I don't really want to move the Open and header management into the subVI; I just want to hide the URI creation and JSON parsing complexity from the top level.

Is there a workaround? Am I missing something?

WebVIs currently don't support dropping typedefs on the panel (error cluster is a special case). Typedefs *can* be used on the diagram and they can be used on the connector pane as well.

HTTP Client Handle is a typedef type, and hence it cannot be dropped on the panel as of today. But you should be able to use it from subVI as shown in the gif.

Ah, okay. I'm not used to the idea of block diagram-only controls. I'll give it a try.

Thank you.
