Jacopo Cappellato commented on OFBIZ-6057:
------------------------------------------

Until it will be closed it will disappears from the release notes, even the ones of the releases
that are already fixed.
This is what I meant.

> In order to fix OFBIZ-2120, code was added to the applications/order/webapp/ordermgr/quote/ViewQuoteItemInfo.ftl
file at lines 53 through 57, with the offending line being at 5:
> https://github.com/apache/ofbiz/blob/trunk/applications/order/webapp/ordermgr/quote/ViewQuoteItemInfo.ftl##L56
> Here is the commit: https://github.com/apache/ofbiz/commit/27253c4667e87721212fa8955d75c74a0d171c73
> This ends up causing the following error:
>      [java] freemarker.core.InvalidReferenceException: The following has evaluated to
null or missing:
>      [java] ==> null  [in template "component://order/webapp/ordermgr/quote/ViewQuoteItemInfo.ftl"
at line 56, column 40]
>      [java] 
>      [java] ----
>      [java] Tip: If the failing expression is known to be legally refer to something
that's null or missing, either specify a default value like myOptionalVar!myDefault, or use
<#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only
cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault,
(myOptionalVar.foo)??

>      [java] FTL stack trace ("~" means nesting-related):
>      [java] 	- Failed at: #assign product = null  [in template "component://order/webapp/ordermgr/quote/ViewQuoteItemInfo.ftl"
at line 56, column 21]
>      [java] 	- Reached through: #list quoteItems as quoteItem  [in template "component://order/webapp/ordermgr/quote/ViewQuoteItemInfo.ftl"
at line 52, column 13]
> The main reason for this is because there is no concept of "null" in FreeMarker 2.3,
as the following thread explains: http://ehc.ac/p/freemarker/discussion/2346/thread/85da30a4/
 Not sure how to go about fixing this error, the thread suggests setting the variable to the
string "null".
> There are other instances of this bug as well:
> $ grep -r "<#assign" * | grep "= null"
> applications/order/webapp/ordermgr/return/returnItems.ftl:                 <#assign
returnItemSubTotal = null >  <#-- otherwise the last item's might carry over -->
> applications/order/webapp/ordermgr/quote/ViewQuoteItemInfo.ftl:                    <#assign
product = null> <#-- don't drag it along to the next iteration -->
> applications/accounting/webapp/accounting/reports/DepositSlip.fo.ftl:               
                <#assign creditCard = null/>
> framework/webtools/webapp/webtools/datafile/viewdatafile.ftl:        <#assign lastRecordName
= null>
> Reproduction Steps:
> 1) Visit http://demo-stable-ofbiz.apache.org/ordermgr/control/FindRequest
> 2) Click "New Request"
> 3) Set
> 	- Cust Request Type Id = Request for Quote
> 	- Requesting Party = DemoCustomer
> 	- Cust Request Name = Test Request
> 	- Description = This is a test request
> 4) Click "Sumbit"
> 5) "Create Quote from request"
> 6) error will appear
