Hi everyone,

I've a little question about scripting i've try to make a script who  
adds a new object if it doesn't exist but doesn't works.

{  
object {  
tag : value,  
tag2 : value  
},  
tag : value,

```
object2 { tag : value }

```

}

I want update this things. I want create a new object if doesn't exist  
and add the new tag/value into but if object exist i just want add the  
tag : value.

For example i've : $myObject = "foo"; $tag = "bar"; $value = "val";

I want create the sructure foo { bar : val } and add it into my  
index.

I've try this script but doesn't works :

if(ctx.\_source.$myObject){  
if(ctx.\_source.$myObject["$tag"] == null){  
ctx.\_source.$myObject["$tag"] = "$value"  
}  
else {  
ctx.\_source.$myObject["$tag"] += " $value"  
}  
}  
else {  
ctx.\_source.$myObject["$tag"] = "$value"  
}

So i don't understand why it doesn't work. Someone ?

Ah, wrong backslash into this code, but it's not the problem.

Yes, it should be possible. If you have problems with the default mvel  
lang, install the javascript plugin and use it instead.
