[QGIS-Developer] R: refactor fields doesn't accept expressions

2017-09-22 Thread Niccolò Marchi 
Hi Andreas,
unfortunately I never used it in this way (with formulae) before: all the 
previous times I was simply adding empty fields or deleting useless ones.

A further minor issue related to the alg: when selecting the field type, 
“double” and “data” are repeated twice.

An improvement could be also adding the NULL value by default when a field is 
created. Does it make sense?

Should these notes be added to your issue or separated into other tickets?

All the best,

Niccolò

Hi Niccolo,

I ran into the exact same problem yesterday. I opened an issue:

https://issues.qgis.org/issues/17170

Are you sure that this worked in earlier QGIS versions? It would help to know 
that.

Hi all,
I'm using 'refactor fields' in the modeler.

Once I've loaded the fields from a shp and then added some new ones, I'm not 
able to add a formula (e.g. 'to_int(substr("MM_GG", 1,2))' ) to the latter ones 
because it's recognised as wrong in the Expression dialog. Furthermore, the 
Expression dialog doesn't recognise any field in the label 'Fields and values' 
and simply shows 'NULL'.
BTW, if I write the formula directly in the box without using the expression 
dialog and then run the model, it works smoothly.
Are those intended behaviours?

i just updated from 2.18.11 to .13 .

all the best,

Niccolò

Hi Niccolo,

Perhaps you can open separate issues.

Thanks,

Andreas
