I am upgrading XWIKI from 1.1 to 1.8 in my sites.
And I use Groovy for the user rights module.
When I update the user rights, errors occurs:
Error number 4001 in 4: Error while parsing velocity page
MyNetcipia.PlaceRightsConfirmation
Wrapped Exception: Failed to evaluate content with id Place Rights
Confirmation
com.xpn.xwiki.XWikiException: Error number 4001 in 4: Error while parsing
velocity page MyNetcipia.PlaceRightsConfirmation
Wrapped Exception: Failed to evaluate content with id Place Rights

I see one sentence:
Wrapped Exception:
org.apache.velocity.exception.MethodInvocationException: Invocation of
method 'updateRights' in class PlaceManager threw exception
java.lang.NullPointerException: Cannot invoke method getDocument() on null
object @ MyNetcipia.PlaceRightsConfirmation11,15
I find there is null in Groovy:(Italic and bold are null value)
public boolean updateRights(String space) {
Document doc = new
Document(wiki.xWiki.</b>getDocument(getRightsPage(space),context.context),context.context)
if ((doc!=null)&&(!doc.isNew())) {
for (obj in doc.getObjects("XWiki.XWikiGlobalRights")) {
doc.removeObject(obj)
}
doc.saveWithProgrammingRights()
}
boolean update = false;
if (doc!=null) {
update |= updateRights(space, "view",
doc.newObject("XWiki.XWikiGlobalRights"))
update |= updateRights(space, "edit",
doc.newObject("XWiki.XWikiGlobalRights"))
update |= updateRights(space, "comment",
doc.newObject("XWiki.XWikiGlobalRights"))
if (space=="") {
// Make sur the admin rights is set
update |= addAdminRights(doc.newObject("XWiki.XWikiGlobalRights"))
}
} else
return false;
if (update)
doc.saveWithProgrammingRights()
return true;
}
But I cannot find which causes the null value and how to avoid this.

New subject: [xwiki-users] Groovy Errors
Where is wiki being set in Groovy? It's not being set in the method you show.
This looks like a typo to me. Shouldn't you be using xwiki instead?
It looks to me that you haven't set a class variable for xwiki (or wiki if
thats the true object variable being used). Without it being set, it will
default to null.
class groovyClass {
def xwiki;
void setXWiki(xwiki) {
this.xwiki = xwiki;
}
// now you can use xwiki in other methods of the class.
...
}

I see one sentence:
Wrapped Exception:
org.apache.velocity.exception.MethodInvocationException: Invocation of
method 'updateRights' in class PlaceManager threw exception
java.lang.NullPointerException: Cannot invoke method getDocument() on null
object @ MyNetcipia.PlaceRightsConfirmation11,15
I find there is null in Groovy:(bold is null value)
public boolean updateRights(String space) {
Document doc = new
Document(wiki.xWiki.getDocument(getRightsPage(space),context.context),context.context)
if ((doc!=null)&&(!doc.isNew())) {
for (obj in doc.getObjects("XWiki.XWikiGlobalRights")) {
doc.removeObject(obj)
}
doc.saveWithProgrammingRights()
}
boolean update = false;
if (doc!=null) {
update |= updateRights(space, "view",
doc.newObject("XWiki.XWikiGlobalRights"))
update |= updateRights(space, "edit",
doc.newObject("XWiki.XWikiGlobalRights"))
update |= updateRights(space, "comment",
doc.newObject("XWiki.XWikiGlobalRights"))
if (space=="") {
// Make sur the admin rights is set
update |= addAdminRights(doc.newObject("XWiki.XWikiGlobalRights"))
}
} else
return false;
if (update)
doc.saveWithProgrammingRights()
return true;
}
But I cannot find which causes the null value and how to avoid this.

I am upgrading XWIKI from 1.1 to 1.8 in my sites.
And I use Groovy for the user rights module.
When I update the user rights, errors occurs:

I see one sentence:
Wrapped Exception:
org.apache.velocity.exception.MethodInvocationException: Invocation of
method 'updateRights' in class PlaceManager threw exception
java.lang.NullPointerException: Cannot invoke method getDocument() on null
object @ MyNetcipia.PlaceRightsConfirmation11,15
I find there is null in Groovy:(bold is null value)
public boolean updateRights(String space) {
Document doc = new
Document(wiki.xWiki.getDocument(getRightsPage(space),context.context),context.context)
if ((doc!=null)&&(!doc.isNew())) {
for (obj in doc.getObjects("XWiki.XWikiGlobalRights")) {
doc.removeObject(obj)
}
doc.saveWithProgrammingRights()
}
boolean update = false;
if (doc!=null) {
update |= updateRights(space, "view",
doc.newObject("XWiki.XWikiGlobalRights"))
update |= updateRights(space, "edit",
doc.newObject("XWiki.XWikiGlobalRights"))
update |= updateRights(space, "comment",
doc.newObject("XWiki.XWikiGlobalRights"))
if (space=="") {
// Make sur the admin rights is set
update |= addAdminRights(doc.newObject("XWiki.XWikiGlobalRights"))
}
} else
return false;
if (update)
doc.saveWithProgrammingRights()
return true;
}
But I cannot find which causes the null value and how to avoid this.
We have defined XWIKI but xwiki.xWiki is null.
So the error : java.lang.NullPointerException: Cannot invoke method
getDocument() on null object @ MyNetcipia.PlaceRightsConfirmation11,15
occurs.

Now it works.
Thank you for all the help!
