Hello all,

My intention is to get search help for the field directly from sap system, Not through hard coded values.But when i click on drop down box, its giving me the following exception. Can any one figure out the problem and give the solution?

Hi Deepti,

How did you implemented value Help Drop Down box ?

Please provide us with the implementation code and the context varaiable details so that i can give clear idea .

Sample code for implementing value Help Drop Down box .

==========================================

IWDAttributeInfo manuInfo =

wdContext.nodeMaterialData().getNodeInfo().getAttribute("ManuName");

ISimpleTypeModifiable manuType = manuInfo.getModifiableSimpleType();

IModifiableSimpleValueSet manuValueSet = manuType.getSVServices().getModifiableSimpleValueSet();

manuValueSet.put("1","Val1");

Please let check this and let me know.

Hi Nanda,

Thanks for your reply.

First I directly mapped my context node on the drop-down field from the Form.

Now I followed the tutorial with ISimpleType and it works.

Yes thanks a lot, the problem is solved.

Unfortunally I can't reward you points for this and can not set the toppic to "Answered" because this is not my toppic.
