Databound SelectItem with multiple values

[brunostuder]

I'm using SmartClient 8 (2011-01-05).
On a DynamicForm with a databound SelectItem

{
   name : "classification1",
   titleAlign : "left",
   width : "*",
   required : true,
   editorType : "select",
   multiple : true,
   autoFetchData: false
},

we have a problem with the datatype sent back to the server in case of a update request.
In version 7 the client has sent a list if the user has selected multiple values.
With version 8 the client sends a string with the comma-separated values (e.g. "value1,value2").
Even if the 'previous values' part of the same request still holds a list for this item (e.g. ["value1","value2"].

I will submit the complete Request-XML, the problem is with field 'classification1'

We don't really have a specific format in which we send arrays of Strings, but you can define one via transformRequest().

Adding code to datasource.transformRequest is not very helpfull as the value is allready a concatenated string there.

And there is another Problem:
The SelectItem has a value map. It correctly displays multiple values delivered as List<String> from the backend.
After an update its value is a concatenated String (of the keys). This cannot be displayed correctly by the same
SelectItem as there is no value map entry for such a concatenates String.

Both problems indicate that you've got the field declared as type:"text" but have not set multiple:true.

[brunostuder]

The form-field is declared as multiple=true as written in my first post.
The datasource is also declared as multiple=true like this

{
  name : "classification1",
  title : msg.texts.trainingClassification1,
  type : "text",
  multiple : true
},

This definitely works with the latest (value arrives at transformRequest() as an Array). Please try it out.

I have added this code to my DataSource

         transformRequest : function(dsRequest)
         {
            if (dsRequest.operationType == "update" || dsRequest.operationType == "add") {
               var field = dsRequest.data.classification1;
               if (isc.isA.Array(field)) {
                  this.logWarn("field is Array", "masoft");
               } else if (isc.isA.List(field)) {
                  this.logWarn("field is a List", "masoft");
               } else if (isc.isA.String(field)) {
                  this.logWarn("field is String", "masoft");
                  this.logWarn("my value is |" + field + "|");
                  this.logWarn("i'm multiple " + this.getField("classification1").multiple);
               } else {
                  this.logWarn("field is something else", "masoft");
               }
            }
            return this.Super("transformRequest", dsRequest);
         }

This is the log
