must not modify the datatype of a mapped attribute

Posted on Jan 19, 2005 at 10:21 AM 15 Views

Hi!

I have an inputfield in my WD with extended value help (countryKey and CountryName, coming from R/3). The selected country should be passed to a bapi import parameter mapped in a model, but the problem is that an exception occurs stating that I cannot change the data type of the context attribute because it is mapped to a model.

How is this usually done?

Thanks,

faB

    Hi,

    1. Create sub-node under your model node with cardinality 1..1 (non-singleton used in sample below)

    2. In this sub-node create calculated attribute with the same primitive type as desired attribute has (say, string).

    3. In setter / getter write code that will modify original attribute:

    /* getter */
return element.node().parentElement().getAttributeValue("OriginalModelAttr");
/* setter */
element.node().parentElement().setAttributeValue("OriginalModelAttr", value);

    4. Rebind your input field to newly created attribute, and apply any value set modifications to it.
