removeAspect('cm:lockable') failed

[vincent-kali]

Hi all,
I've created a Web Script to lock/unlock files.
File locking is working fine:

if (!nodeRef.hasAspect("cm:lockable"))
   {// not already locked
   var properties = new Array(2);
   properties["cm:lockType"] = "READ_ONLY_LOCK";
   properties["cm:lockOwner"] = "admin";
   if (nodeRef.addAspect("cm:lockable", properties))
      {//node successfully locked
      nodeRef.save;
      …

But I can't unlock the document using nodeRef.removeAspect("cm:lockable"), because … the document is locked !

Any idea ?

Thanks for your help,

additional comment: unlocking document from share UI works fine.

[mrogers]

you need to unlock the node first.

[vincent-kali]

thanks for your response.
How to do that ? I thought it was made by removing the aspect lockable ….
Am'I wrong ?

[mrogers]

What you are doing is going behind the lock service.   You need to call unlock.   (And lock)

[vincent-kali]

OK. I was starting to write a JS Web Script, but it seems that I need to write de Backend Web Script in Java to access the lock service,
which is NOT accessible in JS.
Could you please confirm this ?

Thanks for your help !

Yes, unlock a node api is available in js

You can use nodeRef.unlock() which internally uses - lockService().unlock(nodeRef)

[vincent-kali]

it works. thanks a lot !
do you know where to find an up to date documentation for js API ?
I checked out a lot of sites but never found anything regarding lockService in JS….
(http://wiki.alfresco.com/wiki/4.0_JavaScript_API, http://wiki.alfresco.com/wiki/4.0_JavaScript_Services_API……)

thanks,
Vincent

Yes, you are referring correct document but I think unlock() is not there in this wiki.

You can directly check  - ScriptNode.java too.

Honestly I'm lost: In JS, calling nodeRef.unlock() works fine,
but calling nodeRef.lock("READ_ONLY_LOCK") throw exception

   org.springframework.extensions.webscripts.WebScriptException - 06180034 Cannot find function lock.
Does it make sense to implement unlock() without lock() ?

thanks for your help,
Vincent
