[mapserver-dev] Mapscript IOError generarted by applySLD call

[Gino Pirelli]

hi mapserver/mapscript

I've a IOError generarted by applySLD call applying this SLD:
https://gist.github.com/luipir/6139610

debugging msSLDApplySLD call I found that it exit with the last line
mapogcsld.c:479 - return MS_SUCCESS;

but an error code returned by python wrapper: _wrap_layerObj_applySLD
to be precise the call:

errorObj *ms_error = msGetErrorObj();

returns:

ms_error->code = 1
ms_error.routine = "msShapeFileOpen()"
ms_error->message=(/mnt/data/PROGRAMMING/FAUNALIA/qgis-plugins/PLUGIN_TEST_DATA/rt_mapserver_exporter/singlejson_alphatest_data/lakes.json)...
ms_error->isreported=0

then wrapper scan ms_error-> code and return error to python... but
applySLD was succesful!

seems related to a preliminary patch:
https://github.com/mapserver/mapserver/issues/3114 applied one years
ago
that piece of code work only with shapefile

I think it could be managed refining the code before applying the
above preliminary patch
