hello  
Newbie here  
.I have a simple dashboard based flow.  
It contains a dropdown node, a button, and a python module I do some back ground work and an output debug node.  
My problem is for an injection node (non-dashbooard flow), this sequence works fine.  
For Dashboard's Dropdown, I select various options from the ui frame (localhost:1880/ui).  
I dont see them displayed if I add a debug node right after dropdown menu node.  
nor I can not get them via msg['payload'] in my python module.

what am i missing here?  
any help please?

here is my flow:

Dropdown Menu --\> (On UI page: user will select a bunch, and click submit)

In the node red editor:

Dropdown node --\> Button node --\> to my custom python node

For my custom python i am using node\_red decoarator, which works fine.

The `debug` node is your friend! Put a `debug` node (set to display the complete msg object) on the output of the `dropdown` node and another on the output of the `button` node.

Now what do you see?
