Jacques Le Roux updated OFBIZ-6249:
-----------------------------------
Description:
This is the contiunation of OFBIZ-6057 which have fixed the case below, I
simply sort of quote its description here to get the idea:
{quote}
In order to fix OFBIZ-2120, code was added to the
applications/order/webapp/ordermgr/quote/ViewQuoteItemInfo.ftl file at lines 53
through 57. This was working with previous version of Freemarker but is in 2.3
a problem at line 56:
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:

{code}
[java] freemarker.core.InvalidReferenceException: The following has
evaluated to null or missing:
[java] ==> null [in template

column 40]
[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)??

The main reason for this is because there is no concept of "null" in FreeMarker
2.3 (after 2.3.19), as the following thread kinda 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".
{quote}
There are still other instances of this bug in:
{code}
applications/order/webapp/ordermgr/return/returnItems.ftl
<#assign returnItemSubTotal = null > <#-- otherwise the last item's might
carry over -->
applications/accounting/webapp/accounting/reports/DepositSlip.fo.ftl
<#assign creditCard = null/>
framework/webtools/webapp/webtools/datafile/viewdatafile.ftl
<#assign lastRecordName = null>
{code}
There is no needs to change R12.04 though it uses Freemarker 2.3, exactly
2.3.19, this is confusing, I guess this issue did not exist in 2.3.19...
But the other null assignments are wrong in trunk and newer branches anyway
