[Aubit4gl-xmlgui] Problem with nested INPUT inside DISPLAY ARRAY

[wh <spa...@gm...>]

Hello,

I have a lot of code which does an INPUT inside an DISPLAY ARRAY. This 
works well with A4GL_UI=TUI, but with XML/VDC Client I got the follwing 
error message:

contexts[context].ui.input.num_field_data=1 last_attr->sync.nvalues=2
too many values sent back

consider the follwing example:

f1.per
<<<
database formonly
screen
{
[a  |b                  ]
[a  |b                  ]
[a  |b                  ]
[a  |b                  ]
[a  |b                  ]
[a  |b                  ]
[a  |b                  ]
[a  |b                  ]
[a  |b                  ]
[a  |b                  ]
}

attributes
a = a;
b = b;

instructions
screen record s[10] (a,b);
>>> 

t1.4gl
<<<
main

define r record a char(30), b char(20) end record
define a array[20] of record a char(30), b char(20) end record
define lv_i integer
define lv_scr, lv_arr integer

for lv_i = 1 to 10
         let a[lv_i].a = lv_i using "##&"
         let a[lv_i].b = lv_i using "&&&&&&&&"
end for

open window w with form "f1"
call set_count(10)
display array a to s.*
         on key(return)
         let lv_arr = arr_curr()
         let lv_scr = scr_line()
         let r = a[lv_arr]
         input r.b without defaults from s[lv_scr].b
         let a[lv_arr] = r
end display

close window w

end main
