#1266: d.vect has problems

Hi!

If using any selection option of d.vect (the list of category values or
the where condition) GRASS-7.0 does not display the vector. The problem
was in r45123 and is still there in r45168.
If I start with no selection option except feature type selection, vectors
are displayed. If I turn on a selection option of a vector - either the
category list or the where condition, the vector is not displayed, other
vectors are visible. After turning off the selection option, the vector is
still non-visible. I tried to turn the vector on and off in the Layer
Manager window and re-render map display - no effect. The vector is still
there - I see the info of vector elements using v.what, however the vector
is non-visible. I tested this problem on three different vectors having
only areas, only lines, and only points.

An early version of GRASS-7 (of Dec 15 or 16, I guess) does not have this
problem.

Hi!

In r45179 I see vectors again. [[BR]]
Thanks a lot!

Hi!

I reopen the ticket, the problem is still there in r45179. [[BR]] Only
vectors from the old saved workspace are visible and selections can be
used. If I remove vector maps of the loaded workspace in the Layer Manager
window and load a vector again then it is visible. After turning on a
selection by category the vector disappears from the display window.
Really, it is still there, I see info about vector elements by v.what,
however the vector is non-visible. [[BR]] No error messages. [[BR]]
The r45185 has the same problem, r44607 has no such problem.

I have tested r45185, r45214, r45303, r45357, r45362, r45396, r45405,
r45592. [[BR]]
The problem is still there. Even if I change in the same d.vector window
the vector map to another and remove all selection criteria (category and
where conditions), this one is also non-visible. The only way to get it
visible is to close the d.vector window and add in the Layer Manager a new
vector layer. I can use selection criteria in r44607 which I am still
using.[[BR]]

The problem was still there in r45721, r45915, r46101, and r46198. [[BR]]
There is some change in r46317, now I got an error message.

% make clean [[BR]]
% svn cleanup [[BR]]
% svn up [[BR]]
At revision 46317. [[BR]]
% ./configure --enable-shared --without-mysql --without-sqlite --with-gdal
--without-fftw --with-postgres --with-postgres-includes=/usr/include/pgsql

libs=/usr/lib --with-geos=/usr/local/bin/geos-config [[BR]]
% make [[BR]]
% ./bin.i686-pc-linux-gnu/grass70

I load a raster and a vector of 64 areas. [[BR]]
The selection condition for a category (a present category) returns an
error message in the Command console, no change in the display window.

Comment(by cmbarton):

This may or may not be part of the same problem. But it seems close enough
that I'll add this report here for now.

I just recompiled GRASS 7 at r47086,

Vectors do display after doing a v.build. But none of the column selection
controls in d.vect seem to work. Likewise, the color by random colors does
not work either. I had the vector disappear on me once, but it seems to
display OK now.

Interestingly, I get the error reported in the comment preceding this one
if I use d.thematic.area and get any of the inputs wrong.

Several changes have been done in vector modules since that. I do not know
which of them solved the problem but in r47868 vectors do not disappear
any more. [[BR]]
Thanks to developers!
