[QGIS-Developer] multipartToSingleParts via code

[Stefano Masera]

Thanks Nyali. 
The reason is that if I use processing it doens't work correctly. 
In details, if I write: 

import processing 
processing.runalg("qgis:multiparttosingleparts", input1, output1) 

The plugin runs correctly only the FIRST time. 
Then, when it finishes, if I run again the plugin choosing an input2 vectorlayer, the processing algorithm doesn't see the input2 and my ouput remains output1. 
It's crazy! 
It's something like a bad refresh.. 

If you have another solution.... 

Thank you very much. 

Stefano

Any particular reason why? 

In any case, I'd suggest copying the code used by processing: 
https://github.com/qgis/QGIS/blob/release-2_18/python/plugins/processing/algs/qgis/MultipartToSingleparts.py#L66
