hi friends,
i am binding input_feild with the attribute vkorg
it was giving error
The following error text was processed in the system ECC : Adapter error in &VIEW_ELEMENT_TYPE& "IP" of view "ZZZ_TEST13.MAIN": Context binding of property VALUE cannot be resolved: Node MAIN.1.SALES does not contain any elements
The error occurred on the application server csslecc_ECC_01 and in the work process 0 .
The termination type was: RABAX_STATE
but i am giving the cardinality 1 to 1 for the node it was giving solution..
why we are giving 1to1 here...?
i am in confusion what is cardinality & what is selection..?
can anyone explain me in detail,,,,,
regards,
karunakar
Hi Karunakar,
Collection Cardinality or Node Cardinality is a set of two values that define the minimum and maximum number of elements that a node may hold at run-time and is represented as 0..1, 1..1, 0..n, 1..n.
The value on left denotes the minimum number of elements that a node must have at runtime and the value at right denotes the maximum number of elements that a node may have.
Selection Cardinality is again a set of two values like node cardinality but denotes the number of elements that may be selected at run-time. Selection cardinality must not violate Node collection cardinality i.e. if node cardinality is 0..1 0r 1..1, it is invalid to specify 0..n or 1..n as selection cardinality.
Pleae check this...

Hi,
Yes, The cardinality defines how often a node is to be instantiated at runtime u2013 that is, how many elements of this node are available at runtime. Selection means you may slect mulitple or single based on cardinality.
For example in table if you want to select multple records you have to give 0-n or 1-n cardinality.
Cheers,
Kris.
for cardinality 1..1, the context element will be implictly created by WD framework
for cardinality 0..1/0..n, the context element has to be explicitly created in the code.
and for the inputfield, there should be an context element instance available in the context node.
