How to use a field using the user suggestion widget ?

[pibou_Bouvret]

I have a field called reviewers (multi valued string) it is populated thanks to the user suggestion widget i d like to use its content for a setACE operation in a chain but i get a casting error :

No type adapter found for input: class [Ljava.lang.String; and output class java.lang.String

I already made it, but can't remember how 😞

Did you try the run for each operation with a sub operation.

unforunately, i'm running a 5.4.2 project and the the "run for each " operation seems to be 5.5

[Benjamin_Jalon1 · Accepted solution]

So if you are on 5.4.2, you have 2 solutions :

• Upgrade your Nuxeo to 5.6 😄
• Or if you have some development skills create your operation with Nuxeo IDE.

With Nuxeo IDE it will be really quick to do that :

• I let you look the Nuxeo IDE installation documentation : http://doc.nuxeo.com/x/ZYKE

• Then you create a new Nuxeo Plugin Project (click on the yellow button > new Nuxeo Plugin name it > next > next )

• Create a new Operation (click on the yellow button > new Operation > name it > Next > Next )

• And finally you fill the operation :

  @Operation(id = YourOpertion.ID, category = Constants.CAT_SUBCHAIN_EXECUTION, label = "Run For Each", description = "") public class YourOpertion {

   public static final String ID = "YourOpertion";
  
   @Context
   protected OperationContext ctx;
  
   @Context
   protected AutomationService service;
  
   @Param(name = "id")
   protected String chainId;
  
   @Param(name = "list")
   protected String listName;
  
   @Param(name = "item", required = false, values = "item")
   protected String itemName = "item";
  
   @Param(name = "isolate", required = false, values = "true")
   protected boolean isolate = true;
  
   @OperationMethod
   public void run() throws Exception {
       Map<String, Object> vars = isolate ? new HashMap<String, Object>(
               ctx.getVars()) : ctx.getVars();
       OperationContext subctx = new OperationContext(ctx.getCoreSession(),
               vars);
       subctx.setInput(ctx.getInput());
       for (Object value : (Collection<?>) ctx.get(listName)) {
           subctx.put(itemName, value);
           service.run(subctx, chainId);
       }
   }
  

  }

That's what i was about to do.

Backporting new feature is bad...

Feel free to contribute an addon on github for missing operations
