this didn't happened in QGIS 2.2

Hi,

i try to find similar problem byt i don't see.
I use Win8.1 and try on Win7.
When i try to delete tile with "List unique values" then i have this error:

Traceback (most recent call last):
  File "D:/Geodezja/QGISCH~1/apps/qgis/./python/plugins\\processing\\modeler\\ModelerGraphicItem.py", line 361, in mousePressEvent
    self.action()

    val = self.algOutputs[index][out.name]
KeyError: 'TOTAL_VALUES'

Wersja Pythona:
2.7.5 (default, May 15 2013, 22:44:16) [MSC v.1500 64 bit (AMD64)]

Wersja QGIS:
2.4.0-Chugiak Chugiak, 8fdd08a

But in QGIS 2.2 i can delete this tile and i don't have error.
Ok, i saved my model without "List unigues values" and execute in QGIS 2.4 then in log i see:

maybe you have on old Processing version masking the new one, where this issue is fixed (works here).

Delete the folder

c:\\users\\yourusername\\.qgis\\python\\plugins\\processing

if you have one, and test again.

#3 Updated by Marcin Bochinski over 10 years ago

yeah, I know. I tried this. Also I tried on a few computers. There is the same problem.

then please attach sample data (and specify what column to test).

#5 Updated by Marcin Bochinski over 10 years ago

I'm sorry but I can't attach files. These are the company's files. But first error "Traceback..." i have without any data.

does it happens if you install qgis in a standard folder (not in D:/Geodezja/)?

does it happens if you use as input not a .gdb file?

#7 Updated by Marcin Bochinski over 10 years ago

Yeah i try install to standard folder, also i try simple and advance install.

I think that "traceback.." error has something common with wrong save file. Now i use qgis 2.2 and there when i add new algrithm, save my model and open again open model i see "traceback..." error. But I come back to previous version and again and the same algrithm and i don't have error.
Ok, I attached small section of my model with "traceback ..." error on QGIS 2.4 when i try delete "List unique values" (no problem on qgis 2.2).

Second thing. I saved my input files to .shp and also don't work and i saw "[Errno 9] Bad file descriptor". In this model i use Extract by attribute, when i choose other attribute then i see error on other algrithm.

I changed the title and description of the ticket, to be more clear.

For the second issue you should file a separate ticket, with sample model and data attached.

it is fine on master.
