Hi, Using latest node red 1.1.2 with dashboard 2.23.0 I'm using the multiple selection feature - i.e. inputting to the node a list of options (msg.options). Sometimes when I select one or more values - the msg.payload shows more options ?? Also if I dont select anything - the msg.payload still shows one selection. Here is a simple example which shows the bug: Try injecting different options, select some in ui and watch the output messages.

Thanks! Edited the code as JSON

Using your flow, can you provide a step by step of how to cause the issue?

Select the first inject: 1,2,3. Select in UI 1 & 3 for example. Then inject the second option: 4. Select in UI 4 Then inject the empty options. Inject again the 1,2,3 . In the UI , press the dropdown but dont select any value. msg.payload still shows an array of size 1 with one of the values

yes - def looks like a bug. When using multiple select it doesn't clear the "old" selected values if new options are sent. Well spotted. Thanks.

fix now in dashboard master - not yet on npm.

Great!. Will update when available in npm

Hello, I've updated to the dashboard 2.23.1, which fixed the multiple selection bug (old history), but now I noticed a new bug... When you have values & labels (such as the simple flow shown below) - it outputs wrongly the labels instead of the values.. [{"id":"456c58b2.68d648","type":"ui_dropdown","z":"3a8437c5.8f2d38","name":"","label":"","tooltip":"","place":"Select option","group":"c64fd4cd.83f2d8","order":5,"width":0,"height":0,"passthru":false,"multiple":true,"options":[{"label":"zero","value":0,"type":"num"},{"label":"one","value":1,"type":"num"}],"payload":"","topic":"","x":240,"y":158,"wires":[["333fa5ae.b00bea"]]},{"id":"333fa5ae.b00bea","type":"debug","z":"3a8437c5.8f2d38","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","statusVal":"","statusType":"auto","x":479.5,"y":160,"wires":[]},{"id":"c64fd4cd.83f2d8","type":"ui_group","z":"","name":"data1","tab":"e25f6f05.d09e6","order":1,"disp":true,"width":"8","collapse":false},{"id":"e25f6f05.d09e6","type":"ui_tab","z":"","name":"info","icon":"dashboard","order":1,"disabled":false,"hidden":false}]

aaargh... apologies - 2.23.2 will be there in a moment...

Hi and welcome to the forum! You'll need to edit your message to format the flow file JSON properly. Otherwise it cannot be imported due to broken characters.
