deltaX/deltaY properties not set when using handler

[SterlingButters]

This appears to be the case in the following example where deltaX/deltaY properties always take on value of 0:

import dash
import dash_html_components as html
from dash.dependencies import Output, Input, State
import dash_core_components as dcc
import dash_daq as daq
import dash_draggable as drag

import sd_material_ui

external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']

app = dash.Dash(external_stylesheets=external_stylesheets)
app.config['suppress_callback_exceptions']=True
# A FlatButton on Paper
app.layout = html.Div([

    drag.dash_draggable(id='dragger',
                        handle='.handle',
                        defaultPosition={'x': 200, 'y': 0},
                        children=[
                            html.Div([

Perhaps there are conflicts from coexisting/nested components? Needs evaluation

[xhluca]

Hmm could you try rewriting the app with all components in the layout?

[SterlingButters]

Ill try that out and post back

[SterlingButters]

Issue not resolved but found a workaround for goal - will post PR here soon
