----------------------------------------------
Key: OFBIZ-4393

Project: OFBiz
Issue Type: Bug
Components: framework
Affects Versions: SVN trunk
Environment: Rev 1165137

------------------------------------
FWIW I prefer Adrian's way. My patch aimed for the minimum change needed to fix the identified and testable problem. I would have done it Adrian's way if I was confident there were no side effects.

hi, Adrian,
It's better to process "this.relFieldName" as so, since it's absent value is empty string not null either.
or you can ref OFBIZ-4523, I submited that case 2 days ago.

-------------------------------
Attachment: OFBIZ-4393-view-entity_condition-expr_null.patch
This patch replaces relevant tests for null with UtilValidate.is(Not)Empty.
IMPORTANT: if any code relies on a missing value attribute being converted to an empty string that is then used, then this patch will break that. I did look, and couldn't find any such code OOTB.

hi, Adrian,
It's better to process "this.relFieldName" as so, since it's absent value is empty string not null either.

-----------------------------
I suggest to revert r1195042. It will make things more clear: if the value is null and relField is null, then the right hand value will be treated as "null" value.

Anne Jessel commented on OFBIZ-4393:
------------------------------------
The point is that the code quoted by Leon will never be executed, because 'value' will never be null. If value is absent in the xml, then it is read as an empty string. value is intialised using org.w3c.dom.Element.getAttribute() which never returns null, according to the documentation.

------------------------------------
Since a comparison with an empty String instead of a null value is unlikely, I agree with Anne that in a view entity the distinction is irrelevant. Unless there are any objections, I will commit the change.

Leon commented on OFBIZ-4393:
-----------------------------
It has been able to handle null before.
According to original design (I guess), if ommit value and relFieldName attributes in condition-expr, then it will be looked as "null". Then, while the operator is "=" or "<>", the condition will be converted to "is null" and "is not null" respectively. See code pasted below:
{code:java}
} else if ( value == null && this.relFieldName == null && (this.operator == EntityOperator.EQUALS || this.operator == EntityOperator.NOT_EQUAL)) {
return EntityCondition.makeCondition(lhs, this.operator, null);
} else {
{code}
But donno from which revision, the input value of absent value and relFeidlName attributes were converted to empty string (""), not "null" itself, then, now, "view entity condition-expr doesn't handle null".

Anne Jessel commented on OFBIZ-4393:
------------------------------------
On consideration, I don't think the change in behaviour is a major problem. This patch supports EQUALS with null, which the previous code did not support. IMO comparisons with null are very useful. However we lose the specific NOT_EQUAL with empty string, IMO an uncommon test, especially in a view-entity. Overall a big gain, but perhaps not yet a perfect solution.

This is a bug, so this should be go in branches as well(10.04 and 11.04).
I have tested it for release10.04 (did manual merge) and it works fine.

I have added the releases, I can backport if necessary

Anne Jessel commented on OFBIZ-4393:
------------------------------------
I've tested a combination of Adrian's approach and Leon's comments regarding relFieldName, and uploaded a new patch. I can confirm it works for my use case. A condition-expr in a view-entity that has no value or rel-field-name will now correctly compare with null.
In reviewing the relevant code, I did notice a potential change in behaviour with this approach. Because an absent value and value="" are treated the same way, a NOT_EQUAL comparison with the empty string will be treated as a NOT_EQUAL test with null instead.

Anne Jessel commented on OFBIZ-4393:
------------------------------------
value="null" definitely doesn't work. It's what I tried first before looking at the code. Is that what should work? The current code compares value variable with null, but I can't see how value can ever be null, as it has the value returned by org.w3c.dom.Element.getAttribute, which doesn't return null. I can change patch so it looks for String "null" instead of using isEmpty.

----------------------------------------
Maybe we could rather follow Adrian's way on both _this.value_ and _this.relFieldName_ (ie put null if empty at start) and then revert r1195042. The idea behind is it's better to handle the issue at the root, in case some other cases pop up downstream. With a 1485 lines long file you never know...
