Button calls wrong Javascript

[PtrNrs]

As shown in this video, when I construct a simple form with two buttons, B1 & B2, the first listed B1 runs B2's Javascript and B2's JS is OK. Swap the buttons (B2 then B1) and B2 runs B1's JS.

This is behaviour somewhat intermittent - when I first constructed the form on Mac MAMP, it performed correctly and then reverted to the above behaviour for no reason I could determine.

I have also seen a button try to execute the JS assigned to a dropbox in the same form.

The HTML looks OK, but I suspect the JS function dispatchEvent() because

Fabrik.blocks['form_140'].dispatchEvent('button', 'ztest_buttons___Button1', 'click', 'alert('Button 1');');
Fabrik.blocks['form_140'].dispatchEvent('button', 'ztest_buttons___Button2', 'click', 'alert('Button 2');');

assigns both buttons Button 2's JS while . . .

Fabrik.blocks['form_140'].dispatchEvent('button', 'ztest_buttons___Button2', 'click', 'alert('Button 2');');
Fabrik.blocks['form_140'].dispatchEvent('button', 'ztest_buttons___Button1', 'click', 'alert('Button 1');');

assigns both buttons Button 1's JS. ie the order of the dispatchEvent calls changes its behaviour.

The above page is http://joomlatrain.net.au/index.php?option=com_fabrik&view=form&formid=140&Itemid=312.

I've also extracted the HTML to http://joomlatrain.net.au/fabrik_button_test_1_then_2.html (calls the Button 2 JS for both buttons).

Then I reversed the dispatchEvents() calls to create
http://joomlatrain.net.au/fabrik_button_test_2_then_1.html (calls the Button 1 JS for both buttons).

Spooky huh?

Seems to work for me see this screen recording http://screencast.com/t/hNOu970rEm
My local test does the same thing - button a triggers button a js, and button b does the same.

ah oh must have cross posted there!

No! This problem is both intermittent and browser dependent.

Yessterday when I loaded the latest Fabrik, the problem stopped and I assumed that it was a temporary bug in that version of Fabrik. So, I closed this thread - now reopened.

Today the problem has reappeared in Chrome & Firefox but not (!) in IE9.

I cleared the Joomla cache (I had already cleared the browser cache several times) and after a while the problem disappeared in Chrome and then in Firefox as well. The delay was long enough to make me doubt a causal connection.

So right at the moment everything is OK. Is there anything I should test if this reappears. Could the Joomla cache cause such problems with the Fabrik event handler? How can I be confident that the problem will not reappear?

 

[rob]

perhaps a browser cache issue? I'm really not sure - it works consistently for me

It's been driving me mad for several weeks and now (fingers crossed) it's been working for me all day too.

Rest assured I'll let you know if it reappears.
