QuickApp crash, failure msg: attempt to index a nil value

[bgs 0]

Hi,

I have developed a QA controlling my roof top roller shutters based on an calculated rolling average value of my PV power plant production. The QA worked for nearly 1 day and crashes since then.

 

Here is the trace I get:

The last trace before crash is when I try to update the QA value.

 

Here is the code for QuickApp:onInit():

I would highly appreciate any hint where to search.

 

Thanks

Unfortunately, it crashes inside Fibaro's own code for Device...

However, what most likely cause it is that you call some of your QuickApp functions the wrong way

You define functions with function QuickApp:name(...) ... end

but you call them with self:name(...) ... end

Thanks a lot for your help. Implementing the change as suggested I found also a bug in my control function.

Unfortunately I wasn't yet able to resolve the QuickApp crash when I try to update the value using

As intermediate workaround I have currently disabled the update, but I still want to resolve it. As attached the QA works besides the missing value update.

 

 

Attached is the current version of my device file (as json) as well as the lua code file.

 

I would highly appreciate any further hints from the community.

bug in lua file

Found the bug. I used in QuickApp:onInit following:

Quote

self.updateProperty("value",rolavg)

 

but it should be

Quote

self:updateProperty("value",rolavg)

 

Furthermore I removed "uiview" component from fqa file and uploaded it as new device.

 

Seems now to work.
