spaceTitle = (args.st == "undefined") ? "" : args.st,
spaceDescription = (args.sd == "undefined") ? "" : args.sd,‍‍

Why do you have commas here, and in some other places too?

Cheers,
Ivan.

Hi ivan,
Thanks for ur reply.

i removed the comas in FolderCreate.post.js… the following is my new file.

// Client has requested server-side action

/* Inputs */


/* Outputs */
var resultString = "Action failed";
var   resultCode = false;


         resultString = "Could not create space";
        var spaceName = args.sn;
        var   spaceTitle = (args.st == "undefined") ? "" : args.st;
        var   spaceDescription = (args.sd == "undefined") ? "" : args.sd;
           
         var nodeNew;
         
         if ((spaceName == null) || (spaceName == ""))
         {
            resultString = "Space must have a Name";
         }
         else
         {
            
            var nodeParent = roothome.childByNamePath("/Company Home/User Homes/Demo" + spaceName);
           
         nodeNew = nodeParent.createFolder(spaceName);
           
            // Always add title & description, default icon
            nodeNew.properties["cm:title"] = spaceTitle;
            nodeNew.properties["cm:description"] = spaceDescription;
            nodeNew.properties["app:icon"] = "space-icon-default";
            nodeNew.save();
            // Add uifacets aspect for the web client
            nodeNew.addAspect("app:uifacets");
            if (nodeNew != null)
            {
               resultString = "New space created";
               resultCode = true;
            }
         }
     
   
model.resultString = resultString;
model.resultCode = resultCode;

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

now i'm getting the following error.

any idea?

Hi,

just follow the error code, and see what you can gather from there.

You see that you have an error on line 27, saying that it can't call a method of null. Going to your script, you'll see that line is:


nodeNew = nodeParent.createFolder(spaceName);‍‍

So, nodeParent is null. Now you know your problem lies in:

var nodeParent = roothome.childByNamePath("/Company Home/User Homes/Demo" + spaceName);‍

Try removing the first forward slash, and adding one before 'space name'.

Cheers,
Lista.

hi Ivan,
Thanks for your reply still luck is not reaching.

this is my new code..

var nodeParent = roothome.childByNamePath("Company Home/User Homes/Demo"+ spaceName);‍

i'm trying in this way also… but no luck

var nodeParent = roothome.childByNamePath("Company Home/User Homes/Demo"+"/"+ spaceName);‍

Hi, try :

logger.log("spaceName value : " + spaceName);
companyhome.childByNamePath("/User Homes/Demo/" + spaceName);

(The "log" will tell you if "spaceName" is null… that could be an error)

Where did you get "roothome" from? Try "companyhome" and remove "Company Home" from the path.

Hi Mike,
The actual problem is in the log file it is showing the spaceName=xxx.

But in browser i'm getting space null exception

Re: creating a new space using webscripts

jayjayecl — Thu, 02 Jul 2009 09:45:17 GMT

i changed the line to

   var nodeParent = companyhome.childByNamePath("Demo" + spaceName);
‍‍

I thought your space "Demo" is in "User Homes", not in "Company Home"

Try by iteration :
logger.log("spaceName value : " + spaceName);
var userhomeNode = companyhome.childByNamePath("User Homes");
logger.log("userHomeNode value : " + userhomeNode.name);
var demoNode1 = userhomeNode.childByNamePath("Demo");
logger.log("demoNode1 value : " + demoNode1.name);
var demoNode2 = companyhome.childByNamePath("Demo/User Homes");
logger.log("demoNode2 value : " + demoNode2.name);

etc …

Hi Jay,
I'm trying to do the same whatever you guys suggested. But still no luck.
I'm having the folder Demo under company home.

logger.log("spaceName value : " + spaceName); — it is giving the name of the folder which i'm trying to create

var userhomeNode = companyhome.childByNamePath("User Homes");
logger.log("userHomeNode value : " + userhomeNode.name); – it is also giving the Users Home
var demoNode1 = userhomeNode.childByNamePath("Demo");
logger.log("demoNode1 value : " + demoNode1.name); – it is giving error bcoz there is no space named Demo under Comaopany Home/Users Home/
var demoNode2 = companyhome.childByNamePath("Demo/User Homes");
logger.log("demoNode2 value : " + demoNode2.name); – it is also giving error

in browser it is showing the following error.

The Web Script /alfresco/service/simpleui/document/createSpace has responded with a status of 500 - Internal Error.

Well, you did not understand what I told you by MP.
can you try to adapt what I wrote to your situation ???

If you don't have "Demo" under User Homes, of course this is silly to try

var demoNode1 = userhomeNode.childByNamePath("Demo"); ‍

You should not need anyone to do that :


var demoNode1 = companyhome.childByNamePath("Demo");
logger.log("demoNode1 value : " + demoNode1.name);
etc …
