error message context bindung

[Former Member]

Dear Friends,

I get this error message. All what I have done was I have created a second text input field

within transparent container. Context-Bindung is existing I can see that. The prpoerty value

of the input vlaue has an entry MAIN.ZHEAD.CONTACT.

The Context of the main viwe 'ZHEAD' has just following properties.

Cardinality 0..n

Selection 0..1

Initialization Lead selection yes

Singleton yes

Is ttah maybe the reason.

The following error text was processed in the system E70 : Adaptererror  at INPUT_FIELD "ANSPR" of the View "Z_CBD.MAIN": Context-Bindung des Properties VALUE kann nicht aufgelöst werden: Node MAIN.1.ZHEAD does not contain any elements 
The error occurred on the application server apssap14_E70_00 and in the work process 0 . 
The termination type was: RABAX_STATE 
The ABAP call stack was: 
Method: RAISE_FOR of program CX_WDR_ADAPTER_EXCEPTION======CP
Method: RAISE_BINDING_EXCEPTION of program CL_WDR_VIEW_ELEMENT_ADAPTER===CP
Method: GET_BOUND_ELEMENT of program CL_WDR_VIEW_ELEMENT_ADAPTER===CP

Hi

Try to change the cardinality to 1:1.Hope it will work.

Thanks

Are there more must have rules such as text-input-field. It can only have

the cardinality 1u20261 .

·        1u20261        Only one element is instantiated.

·        0u20261        At runtime, no more than one element is instantiated, but it is also possible that no element is instantiated.

·        1u2026n        n elements can be instantiated, but at least one element must be instantiated.

·        0u2026n        The number of instantiated elements of the context node can vary.

Cardinality represents the number of elements a node has at the start of the application and maximum number of elements it could have.

It has two parts, Mandatory and Maximum. (1:1)

Mandatory represents the number of elements a node has at the start of the application and

Maximum represents the maximum number of elements it could have during its life time.

Hence the cardinality should be set depending on the data that the context would be holding .

Dear Tulasi that was exactly the solution. Can you please tell me finally why is it exactly

necessary to have the cardinality 1..1 right here.
