Hi Ankur

It seems you are trying to show Binary attribute from RFC model in your table. Check types of attributes in the model and avoid binding Binary attributes to TextView controls.

Hi,

I am getting this error in the following scenario.

I want to save the text fields from an interactive form to SAP through RFC enabled function module. The type in the model and controller is byte[]. I have converted the string attribute from view to save to the model. But the dictionary (model) has this type as Binary. I am going nuts since 3 days due to this.

Pl help.

Hi,

Thanks for the reply !!

I tried removing binary types from my table & now the data is being displayed.

But if I want to show them anyhow, then how to proceed...?

I need to show them in an Input field.

If you need to display Binary field somehow then you can do the following:

- create new calculated attribute as String in the node to which your table is bound

- in the getter-method for the new attribute get Binary value from the backend attribute, format the value somehow according to your need and return value as String here.

- in the setter-method for the new attribute convert string value from input field and set it as Binary to the backend attribute

- bind your table's cell editor to the new attribute instead of back-end attribute

Hi,

The exception says, its trying to format a table field whose datatype is binary. Check the datatype of the field in the variable. If its binary,since it cannot be "displayed" in a table cell, unmap it in the table.

Thanks,
