Hi admin,

For this problem I have created an isolated problem project, FKTest.
It has two tables, table1 and table2.
Table2 has a FK field to table1, set as required

Adding an item to table2 and leaving the FK field empty, does not trigger an error.

Expected behavior: Clicking save will trigger error when no FK value is selected
Actual behavior: Clicking save saves item and leaves FK value empty

Some debugging what I did:

In the jquery.validationEngine.js there is a funciion _validateField.
In this function around line 460 the hidden property is checked: field.is(":hidden")
if (field.is(":hidden") && !options.prettySelect || field.parent().is(":hidden"))
 return false;
This is true for the select input, I did not investigate further.

JS validation

'chosen' library is causing the problem.
In :
helper.php :: headerDeclarations()

If you comment this line, then it works.
JHtml::_('formbehavior.chosen', 'select');

But the problem, is that will disable ALL select fields. I have no idea how to avoid chosen for a particular field.
For the JS, I will not dig more in because I don't want to hack the third-part library, and secondly this might be deprecated in the coming 'Pure' version.

PHP validation
In an other hand, it should at least validate at php level, this is a problem in facts.
I am checking and I tell you.

Do not make it a priority for me, I have created a workaround.
It is better I think to put you effort in the next pure version.

I will try the chosen statement and see what it brings.

Thanx

I have fixed it by adding
<script>
(function($){	
	$("#adminForm").validationEngine('attach',{prettySelect:true,useSuffix:"_chzn"});
})(jQuery)
</script>

in the form for the item (in my case component/fork/view/record/tpml/createrecord_form.php)
But I will take it one step further and fork the headerDeclaration, so I can utilize this on every form.
I did not test it with a relation field, but will soon

Validation also does not work on textarea with rich text editor (ajax validation that is, validation itself works)

Thats works BEAUTIFULLY for the non-ajax select box, many thanks!

Any ideas on fixing the same issue with ajax selectors?

Good question.
It is possible as said by Romkabouter, that the jQuery conflict is the problem.

The ajax combo is gonna work much better in the "Pure" version, with a new Ajax mini framework.
This part is already done in my hands, but I cannot publish yet.

For me it seems working well on a fresh install, but you can avoid it at the moment if you have problems.
This is not Joomla standard. I have made this 'added' feature to answer the needs of some very engaged followers customers, but I don't like it that much because with Joomla! it is a pain to achieve it properly. I had many issues there in the past and still it continues to be unstable. So I rewrited all.

In the 'Pure' version, those ajax fields are defined in XML file, and handled by superclass. It is a beauty.
Can't wait to show you that stuff. ... Just hold your breath (again) for a while.
