onFocusLost not firing after requestFocus()?

Classic Servoy
1

I have a field I need to validate, and a method to do the validation.

I’ve set the method as the fields onFocusLost property and in the first instance it works.

But… if the validation fails then the method invokes requestFocus() and it’s at that point that the user can tab out of the field (which, by definition, contains invalid data) without the val;idation failing.

FWIW, Servoy 2.2rc3 on Linux with Java 1.5.0

Any ideas?

Thanks,
Neale.

works fine on 22rc7

Although I think this is working under 22rc3 as well,
maybe you should test on rc7 to be sure.

Still broken for me on 2.2rc7 :-(

Here’s the method I have set as the onfocusLost property of the field:

if (globals.validCcardNum(card_num)) {
	return 0;
}

var theAnswer = plugins.dialogs.showQuestionDialog( 'Invalid Card Num', 'Invalid Card Number', 'Edit', 'Revert', 'Clear');

switch(theAnswer) {
case 'Edit':
	elements.ccnum.requestFocus(false);
	break;
case 'Revert':
	card_num = arguments[0];
	elements.ccnum.requestFocus(false);
	break;
case 'Clear':
	card_num = ''; // FIXME - should this be null???
	elements.ccnum.requestFocus(false);
	break;
default:
}

With invalid data in the field, the ‘Edit’ case brings the focus back to the card number field, but I can then tab straight out of the field. If I go back to that field (mouse or back-tab) then a subsequent attempt to tab out of it encounters the ‘Invalid Card Num’ dialog.

I’ve replaced the first lines of code with

if (card_num=="abc") {
   return 0;
}

…and it’s working as expected.
Could you also check if disabling your global validation makes the script work again?

OK, I used:

if (card_num == 1234) {
	return 0;
}

and it’s still broken for me.

Inserting ```
plugins.dialogs.showInfoDialog(‘Card Number’, card_num, “ACK”)

before that confirms that the method is not called at all in my problem case.

FWIW, Servoy 2.2rc7, Java 1.5.0-b64 (Linux)

Thanks,

BTW this looks like an integer so do “= null”

card_num = ‘’; // FIXME - should this be null???

  1. In order to test, try simplifying your code even more
    pseudo code
if(testnr==123)
{
	var theAnswer = plugins.dialogs.showQuestionDialog( 'Invalid Card Num', 'Invalid Card Number', 'OK');
	elements.testnr.requestFocus(false)
}

No, it’s a string (c/card numbers can be typed with blanks and/or hyphens, typically making groups of four digits). This, of course, should be quite incidental to my problem?

elements.testnr.requestFocus(false)
}

I thought I simplified it further? I put this at the very start:```
plugins.dialogs.showInfoDialog(‘Card Number’, card_num, “ACK”)


As previous, in my problem case (tabbing out of the field after requestFocus(false)) I don't see that dialog - implying that the method isn't fired at all.

Have I missed something in that logic?

Thanks,
Neale.

Can you send me a sample solution?

(renamed from .servoy to get a vaguely sane MIME-type)

Problem exhibits when tabbing out of cc number field on second record, clicking “Edit” then tabbing out of cc number field again (no dialog presented, even though cc num is not valid).

Much better in rc8 :-)
