OK,
I don't have solved everything but I have found the origin of the
stackoverflow...
I coded a Recursive VelocityMacro and apparently variables inside VM macro
are not local and it makes my recursion infinite!!!
Apparently, there is an option in velocity to make local macro variables
have only a local scope. Do you see any problem about this?
I have modified my dbstringlist SQL query to use only one column to be sure
this is the easiest case...
I then add a listitem manually to the list property of the object in my
velocity script. Everything is OK but sometimes the list item appears in the
object editor, sometimes not and i don't understand why yet!
Still investigating!
best regards

multiselect relation storage
hello guys,
I do the following:
- I have a class with a DBStringList property "mylist"
- In a velocity script, I do:
#set($obj = $doc.getObject("MyClass", $mynb)
#set($mylist = $obj.get("mylist"))
#set($mylist = "${mylist}|${mynewlistitem}")
#set($ret = $obj.set("mylist", $mylist))
#set($ret = $doc.save())
- I run this script and I can see in the DB that "mynewlistitem" was
added
as listitem to "mylist" but the item
doesn't appear in the object editor
for
property "mylist" in my document.
- Moreover, I get some rendering exception in contentview.vm when I try
to
access this object in other velocity scripts.
- When I create the link using the Object editor, then everything works
well
but I don't see anything different in the DB
from the previous state.
- I have tried the same with:
#set($obj = $doc.getObject("MyClass", $mynb)
#set($mylist = $obj.getProperty("mylist").getValue())
#set($ret = $mylist.add("${mynewlistitem}"))
#set($ret = $doc.save())
same result...
It seems the Object property is saved but it is not taken into account
by
the object in the document.
Do you any clue for me?
- is the property multiselect? relational storage?
- would the mynewlistitem value be returned by the DB search? Or is it a
new value you want to include manually?
in Object editor, I use the DB search to return this value (which is stored
in DB) plus another string (which is the displayed value)
select myvalue, mystring from ...
In my velocity script, I had this value manually directly accessing the
property... But after that, I verify it has been stored using the Object
editor...
- does the DB query normally return one or two
values?
2 values
- what exactly is the error you receive?
I don't have it here now but this is a kind of StackOverflow in
getRenderedContent()
I will search with the debugger if you don't have any quick idea... In
fact, as my property is well stored in the DB (I have verified manually), I
don't see the wrong interaction between this property and its object in this
case... what's different between accessing the property from the object
editor or from my velocity script?
