"I can accept the restriction of the WKT format, that it can be stored only the
geometry but then should not be allowed the "WKT (set options)" chance."
Indeed, you can save the wkt with attribute. It is just a little bit hidden :
save as csv, choose attributes to export and in the attribute list, check
GEOMETRY ;-)
Event if most code is the same for xyz or wkt import/export, I prefered to
simulate two different drivers because the list of options id slightly
different (you have to define a single column for geometry in the case of wkt
and at least two columns in the case of xy(z) or any other combinaison. But
now, it is just a matter of selecting the right driver csv (set options) or wkt
(set options when you import your files (anyway, you must now what is inside).
IN the current version, wkt (set option) is not proposed for files with
extension txt. I'll add it in the next version.

I have a simple WKT file with an attribute data (like 'proba.wkt' file) where
the geomerty is in the second data field/column.
I have open it with the "wkt (set options)" function into a new project.
I have set the "Column containing WKT geometry" listbox to "2".
That was great: I could see the map and data.
I have saved the project as proba.jmp and I saw the
~~~
<key class="java.lang.String">WKT-Column</key>
<value class="java.lang.String">2</value>
~~~
lines in JMP file so I thought everyhing is OK, but when I tried reopen the JMP
file I got a java.lang.Exception:
> Field 1 is needed for geometry but [] has only 0 fields.
What was wrong...?
It's OK, I tried other way...
Let be the geometry in the first and the attribute data in the second data
field/column (like 'reverse.wkt' file) and open it (with "Column containing WKT
geometry" listbox to "1" option) and save the project (reverse.jmp). There are
the
~~~
<key class="java.lang.String">WKT-Column</key>
<value class="java.lang.String">1</value>
~~~
rows.
When I tried reopen then I got the
> Field 0 is needed for geometry but [] has only 0 fields
exception, similar before but the index is 0...
I am afraid, the JMP files are correct but the loader have wrong about indexing
besause it try load geometry from other column what I have set and stored in
JMP file or what am i wrong with?
