hi,
this is not groovy. in groovy, you don't have to put a $ in front of a
variable. Because velocity is the first parser to render the page, the
code $xwiki... is executed.
your script should be like this :
<%
def timestamp = xwiki.formatDate(xwiki.getCurrentDate(),"yyyyMM")
def oldtime = xwiki.getDate().getTime()-(1000*60*60*24*30)
def olddate = new java.util.Date(oldtime)
def oldtimestamp = xwiki.formatDate(olddate, "yyyyMM")
%>

Subject: [xwiki-users] Dates and Groovy
Hello,
I'm having a hard time manipulating Date objects in Groovy implementation
...
I basically want to get a timestamp of a month ago. For example I get a
timestamp "200611" for now, and I want to retrieve the "200610"
string.
This is what I'm doing:
<%
timestamp =
$xwiki.formatDate($xwiki.getCurrentDate(),"yyyyMM")
oldtime = $xwiki.getDate().getTime()-(1000*60*60*24*30)
def olddate = new java.util.Date(oldtime)
oldtimestamp = $xwiki.formatDate(olddate, "yyyyMM")
%>
olddate contains a modified date (maybe the computation is wrong but for now
it's not my problem). I get an error on last line, a NullPointerException
occurring in the formatDate method. But I logged that olddate is not null
(it contains a Date), so I don't really understand from where would come the
NullPointerException ?????
Many thanks in advance,
Jérémie
