Node Has No Valid Parent Error - Initialization

[Former Member]

Hello please have a look at my context structure. I need to pass the values to a Web Service. These values will also first appear in disabled input fields on my web dynpro screen. How can i initialize these fields with hard coded values?

Context -

Context

- Buyer Party (Node 0..1)

-- Internal ID (Node 0..1)

-- Internal ID (Attribute String)

- Item (Node 0..1)

-- Price Component ( Node 0..1)

-- Price Speicification Code(Node 0..1)

-- Text (Attribute String)

I just want to initialize the two attributes in above context with initial values (hard Coded) to be sent to a service. How do i write my code in the wdDoInit() method?

How is the "singleton" property set for these nodes?

Hi Armin,

I am using Netweaver BPM to develop a process. Therein i can set the cardinality property of the Webdynpro Context nodes using a property window.
