Problems with setting Lead with DropDownByKey and SimpleType-Enumeration

Hi all,

I have got a dropdownbykey-list which is filled by a simple-type enumeration which contains 6 key-value-entries.

I have got the following problem:

After starting the webdynpro-application the second entry of the enumeration should be set as leadselection automatically. How can I realize this?

Thank you in advance for your help?

Best regards, Patrick.
