Tableview not reloading

[robertiii]

I cannot get the second table to reload with data from the first tableview on did select.

import ui
import json
import time
		
songList = []

libraryData = []
serviceData = []
previewData = []
liveData = []

def getJsonSongs():
	with open('songs.json') as in_file:
		new_dict = json.load(in_file)
	for song in new_dict:
		songList.append(song)
		
def setLibrarySongs():
	for song in songList:
		libraryData.append(song)

getJsonSongs()
setLibrarySongs()

@robertiii may i get the json data your using? or a dummy version

[stephen]

really haard to ork with with no data lol and i have no idea how your dictionary is structured

[mikael]

@robertiii, I think your main issue is that tableview_number_of_rows is returning a static value. You should return len(right_list_for_the_datasource).

[robertiii]

Mikael you’re a genius!
