I want to make a contract parameter with MultiSelect, but whenever i open the dialog i get this error : "A control with the name 'Fld1_1_Ids' already exists on the form"

Here's what i did:

[DataContractAttribute,
SysOperationContractProcessingAttribute(classStr(MyUIBuilder))]
class MyContract
{
    List            invoiceIds;


    [DataMemberAttribute,
        SysOperationLabelAttribute('InvoiceId'),
        AifCollectionTypeAttribute('return', Types::String)]
       public List parmInvoiceIds(List _invoiceIds = invoiceIds)
    {
        invoiceIds = _invoiceIds;
        return invoiceIds;
    }
}

class MyUIBuilder extends SysOperationAutomaticUIBuilder
{
    DialogField invoiceIdsField;

    public void postBuild()
    {
            super();

        invoiceIdsField = this.bindInfo().getDialogField(this.dataContractObject(),
            methodStr(MyContract, parmInvoiceIds));
    }
    
    public void postRun()
    {
        super();

        Query                   query1 = new Query(queryStr(MyQuery));
        SysLookupMultiSelectCtrl::constructWithQuery(this.dialog().dialogForm().formRun(), invoiceIdsField.control(), query1);

    }
}

If i use custInvoiceId EDT instead of List, the error will go but the problem is, it won't fit alot of data,

So if i select these Invoices CIV-00001,CIV-00002,CIV-00003... In the debug i will only get this: CIV-00001,CIV- (the data is corrupted and not complete)

Cant figure it out from above information but there is tutorial class 'Tutorial_LookupMultiSelectDialog'.

Please take a look at that, that should help you with this.

this tutorial is for RunBaseBatch, but i tried, but using their way, they are creating a new control not from the contract. So to test if in the service class i'll get all selected values and not corrupted i need to know how can i get the values from a dialog control.

For example : the contract parameter i was able to get them in the service class by saying _contract.Parm()... but what about dialog field how can i get their values?
