Troubleshooting "No Argument Exception" Errors for SAP Applications

Problem: When SAP connection properties bind to personalization keys in the mobile business object (MBO) definition, the generated Windows Mobile application throws a “No Argument exception” error when the user clicks the Submit button in the operation screen during runtime .

Solution:

Open the operation form controller C# file, Generated\Form${Screen.name}Controller.cs.

Find the event handler for the operation actions (Button and MenuItem) , for example:

:
			// button (Submit) click event handler
			internal virtual void SubmitButton_Handler(FormsManagerDataObject dataObject)

Add the following code before ${operation.name}ParameterList.Add(…):

Sybase.Persistence.Connection defaultConnection = Sybase.Persistence.ConnectionManager.Instance.DefaultConnection;
	           PersonalizationKeyManager pkmgr = new PersonalizationKeyManager();
	           pkmgr.Initialize();
	           Dictionary<string, Personalization> pkmap = pkmgr.GetAllPersonalizationKey();
	           pkmgr.Dispose();
	           Sybase.Persistence.ConnectionManager.Instance.DefaultConnection = defaultConnection;
	           ${operation.name}ParameterList.Add(pkmap["<personalization key >"].KeyValue);
	          … …           
			${operation.name}ParameterList.Add(pkmap["<personalization key>"].KeyValue);

                ${operation.name}ParameterList.Add(parameterxxxx);

Replace the <personalization key> variable with the personalization key name that binds with SAP connection property.
For each personalization key that binds to a SAP connection property, you must add the line: ${operation.name}ParameterList.Add(pkmap["<personalization key n>"].KeyValue);
When adding personalization key values, you must follow the sequence that is shown in the MBO definition class ${operation.name} method parameter.

For example, when the method is defined as: public void Createfromdat1(System.String jco_client_passwd, System.String jco_client_user, System.String jco_client_client, System.String jco_client_sysnr, System.String jco_client_ashost,…) ,, the code should be entered this way:

createfromdat1ParameterList.Add(pkmap["<pk of password>"].KeyValue);//first

createfromdat1ParameterList.Add(pkmap["<pk of user>"].KeyValue);//second

createfromdat1ParameterList.Add(pkmap["<pk of clientID>"].KeyValue);//third

createfromdat1ParameterList.Add(pkmap["<pk of Sysnumber>"].KeyValue);//fourth

createfromdat1ParameterList.Add(pkmap["<pk of AppSer>"].KeyValue);//fifth
