Multi-select List Lookup Control - connect to a Multiple Lines of Text variable?

that's not supported by design, see documnetation

why couldn't you store it in regular lookup list field? that could be processed within the workflow either.

Thank you but I am not sure I follow. The only controls that I see that could fit what I want to do is the List Lookup control and the Choice control. However the Choice control doesn't let me get the choices from a SharePoint list that I can tell. Can you elaborate?

ops, I'm sorry, I haven't realized you're talking about site workflow.

my suggestion would work for list workflow.

with site workflow you're unfortunatelly out of luck. you have to find a way how to manage it with single line text variable.

there is an idea on uservoice that already request that functionality, you can vote for it

Haven't tried this yet but it seems like it should be promising: Modify the Start button settings so that  when the Start button on the form is clicked, it calls a JavaScript function. The JavaScript function gets all the selected items in the List Lookup control and pushes them into a Multiple Lines of Text control that is connected to a Multiple Lines of Text variable. Then the workflow can process the Multiple Lines of Text variable as needed. Our policy is to avoid doing "custom" coding for our SharePoint solutions but I don't really see another way.

you may try ...

but if I recall correctly once I wanted to do something similar in the past but I falied. simply, any change made from submit button's click function was not accepted. it looked like there was made a snapshot of form content at the moment submit button was hit and these data were sent to sharepoint, if validation passed. it dindn't accepted any further changes.

I as well tried with 'fake' submit button, which first did my logic and then simulated regular submit button click, but, if I recall correctly, with this scenario I got into troubles with validations. so I gave up to do anything like this.

but as I wrote, you may try. maybe something has changed since my attempts.

let us know how you succeeded.

I tried it and it works! It only took one line of JavaScript to copy the selections from the List Lookup control (the JavaScript variable for the List Lookup control actually points to a hidden textbox that has all the selections appended together) to the Multiple Lines of Text control (which is connected to a Multiple Lines of Text variable). Then inside the workflow, I can parse out the Multiple Lines of Text variable into a collection and process from there. Note that you can only specify a JavaScript variable for the Multiple Lines of Text control if it is visible so I just put a rule on it to hide it. I left the Start button as Save and Submit so it still also does validation. Note that the JavaScript function specified on the Start button is called BEFORE the validation occurs, though.

Hi All,

I have a work around for Connecting a Multi-Select list to a Multi lines Text column.

Step 1 - Create a Single Line Text column and connect the Multi-Select list to the
single line text field. Save and exit the form.

Step 2 - Then go into your list settings and change that Single line text column to Multilines of text.

Have tested this on few forms and works just fine.
