(Updated to include prepend empty option to top of the list)

There is a way that you can get around this by using workflows and Javascript.

In workflows:

We use a custom query activity to query our database for the information that we need. For example, members on an account. Our query returns multiple owners of the account in one string separated by a pipe. Ex. Member1|Member2|Member3

Then we use the "Set Business Variable" activity to push that string to Laserfiche Forms into an empty drop-down field.

In Laserfiche Forms we assign a specific css class to that field. For example: List_of_Owners

Then we use the following JavaScript to separate the string from Workflows out into drop-down field choices. (Replace "List_of_Owners" with whatever you named your css class)

$(document).ready(function () { 
//Compile correct list of Owners in "Person Making Request Field"
//Loop through all options in the drop-down list.
  var options = $('.List_of_Owners option:first-child').text().split('|');
  var index;
  for (index=0; index<options.length; index++) {
    $('.List_of_Owners select.form-item-field').append("<option>"+options[index]+"</option>");
  }
  $('.List_of_Owners option:first-child').remove();
  $("<option>", { value: '', selected: true }).prependTo(".List_of_Owners select.form-item-field");

//Prepend a blank option to the field
  $("<option>", { value: '', selected: true }).prependTo(".List_of_Owners select.form-item-field");

});

That should convert the string into drop down choices like you want.

Hope this helps. :)

Not for nothing, but what I usually do is kick the forms process off from workflow with the other starting variables I want, and if there is a dropdown I want selections to be available for from the workflow, I add a step right before the 'Invoke Business Process' activity to add the multi-value token to a table as a column by iterating through it with a for each value and forming rows in the table.  Then all you have to do is use that table for a lookup when your form loads, and assign that column to your dropdown field.  Its a bit more work, but it does work nicely, as if there is a user task after the process begins, the user will have those selections to choose from, and they were still put there by the workflow so it accomplishes the same thing.

One option could be to run a For Each Value loop and concatenate all your values separated by a brake. Some of the folks in here know this by heart and might put together an example really quick for you I'm sure.

I'll see if I can pull a similar example from some of the work I've done, since this seems like something we might use eventually as well.

Hi,

Actually I'm already doing For Each, but instead of concatenating I'm appending the values to multi-value token %(Members). I'm not sure if multi-value token will fill the dropdown field in forms.

I'm trying to find how to set dropdown field values from workflow using "Set Business Process Variables" activity. Should we pass a multi-value token or a string separated with brake?

What is brake? Sorry couldn't get it.
