Getting error 40405 , NO CHANGES TO APPLY

Question

SOMEHOW THE ERROR IS DISPLAYED IN MY TIGGER WHEN I DO
EXECUTE_QUERY COMMAND. SEE MY TRIGGER BELLOW.
CLEAR_BLOCK(DO_COMMIT);
GO_BLOCK('CW_ENTRIES');
EXECUTE_QUERY;
GO_BLOCK('CW_CHANGES');
EXECUTE_QUERY;
GO_BLOCK('TIME_DETAIL');
This message appeared after I have made some changes but I do
not know when. I have version that works, but it is only fmx
file.
Thanks, for any info.

I think in this case, you issued a commit without actually changing any data, so the commit was not necessary. Many Times I had to do this and did not want to see this error.
What you can do to overcome this is to create a forms 'on error' trigger. Then trap the error like follows -
DECLARE
errnum NUMBER := ERROR_CODE;
errtxt VARCHAR2(80) := ERROR_TEXT;
errtyp VARCHAR2(3) := ERROR_TYPE;
BEGIN
IF errnum = 40301 THEN
Message('Your search criteria identified no matches... Try Again.');
ELSIF errnum = 40350 THEN /* no records found */
null;
ELSIF errnum = 41026 THEN /* FIELD OUTPUITING*/
Message('This field is calculated');
ELSif errnum=40401 then /* double commit somewhere */
null;
ELSif errnum=40505 then /* double commit somewhere */
null;
ELSif errnum=41050 then /* Record has been saved already */
null;
ELSIF errnum=41008 then /* Undefined Keys */
null;
ELSIF errnum=40100 then /* beyond first record */
null;
ELSIF errnum=40200 then /* field protected against update */
null;
ELSIF errnum=40352 then /* beyond last record */
endif;
