B4J Question [B4X Pages] B4XDrawer with CLV with Buttons - Button event does not work

[MrKim]

Pretty much copied from the example.
'load MENU the layout to Root
Drawer.Initialize(Me, "Drawer", Root, 200dip)
Drawer.CenterPanel.LoadLayout("Main")
Drawer.LeftPanel.LoadLayout("MainPageMenu")
[/CODE]
MainPageMenu has a CLV and the CLV_ItemClick event works just fine.
BUT
I added a button and a B4XSwitch (on a pane) from a layout to the CLV.
I added Button_Click and Sw_ValueChanged events to the Main Page from designer but these events do not fire.
The events are trapped because the CLV_ItemClick does not fire if you click the button or the switch.
Clicking the button does nothing, clicking the switch gives the following error.

I'll try to make a simple one. Mine connects to web opens databases requires logins on initiall use etc.....

Since, of course, when I simplified things it worked just fine so I had to duplicate my code more closely to reproduce the problem.
And I solved it but I am not sure it is good practice.
Because the code to populate the CLV gets called from multiple places I had moved that code to a class module. At the time I did this it was a simple CLV.Addtext.

When I decided to make the CLV more complex I needed the to dim one of the views to add text to it and it needed to be in the class module.

The upshot is it works if I move the events to the class module, so the event for the CLV in on the mainpage, but the events for the Views on the CLV are in the class.

I have no idea if this is OK or if it will cause problems - perhaps in B4A or B4i? I have used the 3pagesm with drawer example to demonstrate what I have done.

The drawer is on page 2.

If you bless this mess then I will mark this as solved.

As always thanks for your help.

The views events will be raised in the code module that initialized the views (or loaded the layout with the views). Note that in B4A static code modules cannot handle events.
