Accessing model node with cardianlity 1 to 1 throwing error

[Former Member]

Hello All,

I'm try ing to set values to a model node in the request for a mass update.

in teh model nodes, one of the model node is mandatory with 1:1 cardinality.

i cannot call the currentElement() nor the create and addelement

both throwint the same error as below.

I'm using CE 7.2 engine, and its very critical for me to complete this update.

com.sap.tc.cm.base.exception.BaseModelRuntimeException: No object for mandatory target role 'Position' of model class 'uk.co.apps.bertha.wdj.model.wd.models.managets.PositionWrapper' with cardinality 'ONE' maintained

the generated code, i have a list to which i have to bind this node to, there is no code generated as i see it.

i tried regenerating and it doesnt help.

the following is the complete stack

Thanks for reply,

but i can't understand what is myModel indicates in the below code?

Request_EmployeeManagementLocal_updateEmployee reqMod =

new Request_EmployeeManagementLocal_updateEmployee(myModel);

//Check empl model class will be there , create an object for that

Employee objEmpl=new Employee(myModel);

regards,

Hi,

myModel is the instance of the WebService.

Like,

EmployeeMgmtWSModel myModel = new EmployeeMgmtWSModelModel();

Unfortunately Webdynpro Java F/W cannot handle the list object inside a list object. so the genearated code becomes useless and you will have to write the data to the webservice directly maipulating the model object, though it took a while to figure out, I found this is the best way now.

Thanks for all your inputs.

Cheers

Hi,

How many attributes are there in that Model Node (1...1). Are you setting values to all the attributes?

Try once by setting values to all the attributes.
