So you want to differenciate between a property set to null and a property that does not exist ? If your issue is that the document may not have PR then you can't use custom properties in Contex to passe informations since there won't be any way to access it. Another way that should do it is to set properties in script context using something like: services.component.getInstance(org.xwiki.script.ScriptContextManager.class).setAttribute("DoCleanup", true, javax.script.ScriptContext.ENGINE_SCOPE); and then access it in Velocity using: $DoCleanup On Fri, Aug 1, 2014 at 3:46 PM, Pascal BASTIEN <[email protected]> wrote:

And also, what is your target XWiki version ? Is it really 4.1 ?

Thats because $null is not the Java null, but "something undefined" A few options to check for null are given here: http://wiki.apache.org/velocity/CheckingForNull (however XWiki does not have that $null-tool installed and the other stuff mentioned from Approach 4 down, so you might try "Approach 3" there) (and there a few '$' in front of xcontext missing ;) Clemens

By the way, realizing something, if your objective is to call a macro from velocity to "reinitialize a sandbox", with passing parameters, why don't you just make it a velocity macro ??? In your SandboxTemplate.ReinitSandboxMacro : #macro (reinitSandbox $source $target $doCleanup) ## ... your macro code ... #end And in your scheduler script: {{include reference="SandboxTemplate.ReinitSandboxMacro"/}} ... #reinitSandbox "space1" "space2" "true" You could even make it a wiki macro [1] ...

Hi,

...

2014-08-01 15:42 GMT+02:00 Pascal BASTIEN <[email protected]>:

Yes, my scheduler can contain: xcontext.put("DoCleanup", "true")

...

xwiki.getDocument("SandboxTemplate.ReinitSandboxMacro").getRenderedContent() or this xcontext.put("source", "SpaceTemplate") xcontext.put("DoCleanup", "true")

xwiki.getDocument("SandboxTemplate.ReinitSandboxMacro").getRenderedContent()

or xcontext.put("source", "SpaceTemplate") xcontext.put("target", "SpaceToDeleteAndOverwrite") xcontext.put("DoCleanup", "true")

xwiki.getDocument("SandboxTemplate.ReinitSandboxMacro").getRenderedContent()

I would maybe try to replace the "...getRenderedContent()" by an include macro [1] like:

{{include reference="SandboxTemplate.ReinitSandboxMacro"/}}

include macro renders the document in same context as container document.

[1] - http://extensions.xwiki.org/xwiki/bin/view/Extension/Include+Macro

...

And my SandboxTemplate.ReinitSandboxMacro contain this velocity scipt:

#if ($request.get('source') != $null)

If from outside you use "$xcontext.put", you can't expect it to be available from "$request.get" ;-) You should use "$xcontext.get" here instead.

...

#set ($Source = "$request.get('source')") #else #set ($Source = "SandboxTemplate") #end

#if ($request.get('target') != $null) #set ($Target = "$request.get('target')") #else #set ($Target = "Sandbox") #end

#if ($request.confirm == 'true' || $xcontext.get("docleanup") == 'true')

From where would come this "confirm" request param ? From a scheduler job there will not be such request parameter ... unless you don't talk about the xwiki Scheduler ? [2]

[2] - http://extensions.xwiki.org/xwiki/bin/view/Extension/Scheduler+Application

...

=>My script is launch

This test doesn't work #if (xcontext.get("source") != $null)

Anyway you miss the '$' here --> "$xcontext.get("source") ..." Personnally I usually prefer to write:

#if ("$!xcontext.get('source')" != "")

... but it's a matter of taste...

Sorry, not only a matter of taste, that way you check at once if property is null OR empty string. Depends on what you need of course.

...

...

#set ($Source = "xcontext.get("source")") #else #set ($Source = "SandboxTemplate") #end

To resume: I'm looking for a test to know if a xcontext.get("parameter") exist or not (in a velocity script)

Thxs to all, but I try to explain more clairely :-) From groovy I pass (or not) some parameter at my velocity script and in velocity I simply want to check if my parameter exist or not.
