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
