FlexForm from rpw.ui.forms

I am having trouble creating a basic script to test out using FlexForm from rpw.ui.forms to take multiple user inputs.
I get type error "takes exactly 3 arguments(2 given).

When i Copy the code from the documentation i get the same type of error, but it refers to the script in pyrevit library.

I also tried copying some code with flex form from pyChilizer from github, but get the same problem.

Can someone help me understand what it going wrong here?

And my code:

from rpw.ui.forms import FlexForm, Label, ComboBox, TextBox, Separator, Button, CheckBox

components = [Label("Choose View Template"),
              ComboBox("combobox2", {"Opt 1":10.00, "opt2":20.0}),
              TextBox("textbox1", Text="EIHD"),
              CheckBox("Use same prefix for all views"),
              Button("Create Views")]

form = FlexForm("ViewSet Creator", components)


Hi ,
It looks like your CheckBox is missing two arguments.

Hi @eivhal ,
This is a problem in the flexbox internals;
Try to select a previous version of the ironpython engine.
Let us know if there is a version in which it runs fine

I know this is an old thread, but i ran into the same problem.

For anyone stumbling across this:
Versions that still seem to work is IronPython Engine 277, 278, 279, 2710
Using Custom pyRevit IronPython Engine 2711 starts producing this error.

This is probably the best news ive received all week. :green_heart:

I’ve been breaking my head trying to look for alternatives to RPW to fix all my code that recently broke.

Thank you so much for updating us on this @Jean-Marc

Thanks so much for fixing this!

I finally got around to testing it, and it works fine.
Now the possibilities are endless!
