Tableview_select

Appletrain

I’ve written a custom input form sub-classed from input form dialog. It works fine stand alone. It also works fine when called from a button on my tableview form. When I call it from tableview select, it blows out. Somehow container_view becomes None. I’ve tried everything I can think of, including calling the button action. Any thoughts?

@Appletrain, have you tried decorating the tableview_selected method with @on_main_thread?

Appletrain

@mikael Thanks @mikael, doesn’t help. Same error, same place. What I can’t understand is why it works one place and not another. I stripped every thing out of the two functions so they are doing exactly the same thing. On blows up, the other does’t.

@Appletrain, can you share your stripped-out code?

Appletrain

@mikael, this is about as stripped out as I can make it

def tableview_add(self):
            trxRec = {}
            result = {}      
           # trxRec = {'account': self.selected_account}
            result = bucks_dialog(trxRec)    # this works
        
    def tableview_update(self):
            result = {}
            trxRec = {}
           # trxRec = self.selected_item
            result = bucks_dialog(trxRec)    # this blows out - self.container_view changes to None
        
    def tableview_did_select(self, tv, section, row):
            self.tableview_update()
        
def transaction_action(sender):    # sender is ui.button
    sender.tint_color = 'blue'
    ds.tableview_add()

Bucks_dialog is a custom form_dialogs from dialogs

Error is:

Pythonista3/Documents/Projects/bucks/bucks_form.py", line 217, in trans_type_action
self.container_view.name = segment_names[ind]
AttributeError: 'NoneType' object has no attribute 'name'

self.container_view is none (form_dialog)

@Appletrain, sorry, my faulty memory. You need to decorate the method with @ui.in_background. This will mean that you do not get the method return value in the same thread, so you need to set the tableview values within the backgrounded method, or look at this thread.

@mikael, thank you, that took care of it. I had tried that, but I put it at the update function not the select function.
