The * construct should be: * * CONSTRUCT BY NAME q_que on field1,field2,... * * ON KEY (f7) * IF INFIELD(field1) THEN * CALL fEditAndSelect() RETURNING cod, descri * display descri to field1 * END IF * * ... * END CONSTRUCT * * * The problem is in the fEditAndSelect function. It has an input array and * return one row (return p[i].cod, p[i].descri). The returned values are of * the same type that cod and descri. * * I have verify that the problem is the input array of the function. If * instead of the input array I use a display array or simply I return two * values the construct keeps the value displayed. * * What's happening? We've verified that this is a bug. Don't know if it has a valid bug number, tho. If you are within a CONSTRUCT and call a function which uses the INPUT or INPUT ARRAY, the CONSTRUCT doesn't store ANY more DISPLAYed values from then on. You are correct in changing the called function to use DISPLAY ARRAY.
