OnValidate trigger is executed two times on Page

Ravi_Prakash_Goyal

Hi,

I am getting an strange error on Page. I create a Boolean variable 'testbool' and add it as field on page and write following code on OnValidate trigger of this field

testbool - OnValidate()
testbool := NOT testbool;
MESSAGE('test01');

Surprisingly, the OnValidate trigger is executing two times when I click on Boolean value i.e. above message appears two times. It this a bug in the product? Please help I need to fix it for my current upgrade project.

I am using NAV2013 (Build 7.00.34587). I can see there is a similar Hotfix released (KB 2797787 in Build 7.0.34194) by Microsoft but it does not resolve my issue.

Regards,
Ravi Prakash Goyal

Yes, it's a bug. It should be fixed in some hf. I don't know the number.

Ravi, but what you are trying to achieve by this code?

I checked this in the latest release NAV2013 FP1 (build 7.0.34797.0) also, this is not fixed.

Here is my actual code. The objective here is to reset the Boolean variable 'ScannedIsDefaulBarcode' to its original state if user does not confirm the action. If I don't do that, system will update the changed value to the variable, which is not correct.

Name ConstValue
Text007 Are you sure you want to set Default Barcode field to %1 for the scanned barcode %2.

ScannedIsDefaulBarcode - OnValidate()
IF CONFIRM(STRSUBSTNO(Text007,ScannedIsDefaulBarcode,ItemCross."Cross-Reference No.")) THEN BEGIN
IF ScannedIsDefaulBarcode THEN BEGIN
......
......
END;
END ELSE BEGIN
ScannedIsDefaulBarcode := NOT ScannedIsDefaulBarcode;
EXIT;
END
