Add field EcoResProductCreate Form

Hi, I would like to add the description field from EcoResProductTranslation table in EcoResProductCreate form

I extended this method to map the field to EcoResProductTranslation table.

protected void createData2Controls()
{
next createData2Controls();

data2Controls = conIns(data2Controls,
conLen(data2Controls) + 1,
[tableStr(EcoResProductTranslation), [[fieldNum(EcoResProductTranslation, Description), formControlStr(EcoResProductCreate, WTIProductDescription)]]]);
}

I get this error: Function EcoResProductCreate.getBufferByDataSourceName has been incorrectly called.

This is where I'm blocked. I want to add this table in switch case of getBufferByDataSourceName method, but this method is private, I can't extend it.

Any help or ideas would be really appreciated,

thanks!
Claudia

Ok the solution to this was to use the delegate method in the switch case (default case)
default:
EventHandlerResult result = new EventHandlerResult();
this.getBufferByDataSourceNameDelegate(_formDataSourceName, _itemId, _forUpdate, result);

if (!result.hasResult())
{
throw error(Error::wrongUseOfFunction(funcName()));
}

common = result.result();

We need to create a subscribed method

1- create a class

2- Add a subscribe method, that subscribes to getBufferByDataSourceNameDelegate delegate

[SubscribesTo(formStr(EcoResProductCreate), delegateStr(EcoResProductCreate, getBufferByDataSourceNameDelegate))]
public static void EcoResProductCreate_getBufferByDataSourceNameDelegate(str _formDataSourceName, ItemId _itemId, boolean _forUpdate, EventHandlerResult _result)
{
EcoResProduct ecoResProduct;

select RecId from ecoResProduct
where ecoResProduct.DisplayProductNumber == _itemId;

if(ecoResProduct)
{
EcoResProductTranslation ecoResProductTranslation = EcoResProductTranslation::findByProductLanguage(ecoResProduct.RecId,companyinfo::languageId(),_forUpdate);
_result.result(ecoResProductTranslation);
}
}
