Steps To Reproduce Behavior

  1. Paste the following code in a program (.prg) file and then run the program:
    #DEFINE DBCNAME 	'testdb'#DEFINE TABNAME 	'testtab'CD (ADDBS(JUSTPATH(SYS(16))))CLEAR CLOSE ALLDELETE FILE testdb.dbcDELETE FILE testdb.dc?DELETE FILE testtab.dbfCREATE DATABASE DBCNAMECREATE TABLE (TABNAME) (F1 I PRIMARY KEY, F2 C(8) , F3 C(10), F4 i, F5 i)	CLOSE DATABASES ALL DELETE FILE testdb1.dbcDELETE FILE testdb1.dc?CREATE DATABASE (DBCNAME+'1')CREATE CONNECTION Conn1 ;	CONNSTRING "Driver=Microsoft Visual FoxPro Driver;UID=;" + ;	"PWD=;SourceDB="+ADDBS(JUSTPATH(SYS(16)))+"testdb.dbc;SourceType=DBC;" + ;	"Exclusive=No;BackgroundFetch=Yes;Collate=Machine;Null=Yes;Deleted=Yes;"CREATE SQL VIEW "RV_TESTTAB" ;    REMOTE CONNECT "conn1" ;    AS SELECT * FROM testtab Testtab WHERE Testtab.f1 = ?idDBSETPROP('RV_TESTTAB', 'View', 'SendUpdates', .T.)DBSETPROP('RV_TESTTAB', 'View', 'Tables', 'testtab')*!* Field Level Properties for RV_TESTTAB* Props for the RV_TESTTAB.f1 field.DBSETPROP('RV_TESTTAB.f1', 'Field', 'KeyField', .T.)DBSETPROP('RV_TESTTAB.f1', 'Field', 'Updatable', .T.)DBSETPROP('RV_TESTTAB.f1', 'Field', 'UpdateName', 'testtab.f1')DBSETPROP('RV_TESTTAB.f1', 'Field', 'DataType', "I")* Props for the RV_TESTTAB.f2 field.DBSETPROP('RV_TESTTAB.f2', 'Field', 'KeyField', .F.)DBSETPROP('RV_TESTTAB.f2', 'Field', 'Updatable', .T.)DBSETPROP('RV_TESTTAB.f2', 'Field', 'UpdateName', 'testtab.f2')DBSETPROP('RV_TESTTAB.f2', 'Field', 'DataType', "C(8)")* Props for the RV_TESTTAB.f3 field.DBSETPROP('RV_TESTTAB.f3', 'Field', 'KeyField', .F.)DBSETPROP('RV_TESTTAB.f3', 'Field', 'Updatable', .T.)DBSETPROP('RV_TESTTAB.f3', 'Field', 'UpdateName', 'testtab.f3')DBSETPROP('RV_TESTTAB.f3', 'Field', 'DataType', "C(10)")* Props for the RV_TESTTAB.f4 field.DBSETPROP('RV_TESTTAB.f4', 'Field', 'KeyField', .F.)DBSETPROP('RV_TESTTAB.f4', 'Field', 'Updatable', .T.)DBSETPROP('RV_TESTTAB.f4', 'Field', 'UpdateName', 'testtab.f4')DBSETPROP('RV_TESTTAB.f4', 'Field', 'DataType', "I")* Props for the RV_TESTTAB.f5 field.DBSETPROP('RV_TESTTAB.f5', 'Field', 'KeyField', .F.)DBSETPROP('RV_TESTTAB.f5', 'Field', 'Updatable', .T.)DBSETPROP('RV_TESTTAB.f5', 'Field', 'UpdateName', 'testtab.f5')DBSETPROP('RV_TESTTAB.f5', 'Field', 'DataType', "I")USE rv_Testtab SHARED NODATA=CURSORSETPROP("Buffering",3) && same with 5? "   First Call To AddData"* Add the first record to the table.=AddData(500) ? "   Second Call To AddData"* Add the 2nd record to the table.=AddData(501)RETURN PROCEDURE AddData(lnNewVal)   id=0   =REQUERY("rv_Testtab")   SELECT rv_Testtab   APPEND BLANK   REPLACE F1 WITH m.lnNewVal, F2 WITH ALLTRIM(STR(m.lnNewVal)), ;      F3 WITH ALLTRIM(STR(m.lnNewVal)), F4 WITH m.lnNewVal, ;      F5 WITH m.lnNewVal	   ?

"  Table Update Results: " + IIF(TABLEUPDATE(0,.f.,"rv_Testtab"), "True", "False")      ? "  GETFLDSTATE() In Transaction After Table Update:  "+GETFLDSTATE(-1,"rv_Testtab"),F1   END TRANSACTION    * After the second record has been added and the transaction is done,   * GETFLDSTATE shows that another record has been appended when    * this is not the case.   ? "  GETFLDSTATE() After End Transaction: "+GETFLDSTATE(-1,"rv_Testtab"),F1ENDPROC   					
  2. Examine the results as follows:
    • After the first record is added to the table, the results from GETFLDSTATE after the END TRANSACTION command return all 1s, which indicates that the field has not been edited.
    • After the second record is added to the table, the results for the GETFLDSTATE after the END TRANSACTION command return all 3s, which indicates that the field in the appended record has not been edited.
    • The GETFLDSTATE function reports that another record has been appended to the table even though no record has been added.
