QUESTION NO: 3
Jose is designing web services that will return very large record sets (in the 1000's). He is also designing an IBM Web Experience Factory application to consume them and plans to use Web Experience Factory's Paging features to paginate over the large record sets. How should paging be configured for the web services?

A. Jose should consider implementing a start index and fetch size parameter in his underlying web services that return large record sets. Then in Web Experience Factory he can implement the DataRetriever interface which enables the Paging Assistant builder to return "chunks" from the underlying service rather that marshalling the entire record set into the application server's memory. B. He should simply enable paging in the Data Column Modifier builder. Web Experience Factory automatically chunks the data from the backend web service into the app server memory. C. He should consider using The Chunked Data Retriever builder, which allows you to specify a start index and fetch size before invoking a web service. D. He should use enable the Web Service Call to return a DataRetriever and then add a Paging Assistant builder and point to the variable created by the results of the web service call.

Correct Answer: A

Tara is using the Dojo Inline Edit builder to give the user editing capabilities to a Data Page field. She enabled the Allow Multiple Edits input in the builder. By default, the builder automatically cancels an ongoing edit in the current field if the user selects another field to edit. When automatic canceling is about to occur, the builder fires a client event named processInlineAutoCancel. Tara wants to provide feedback to the user that asks whether they wish to cancel their edits. How can she best accomplish this?

A. She can add a Client Event Handler builder that runs a script where she will set the continueAutoCancel field of the inlineEditState object to true or false based on the users response. B. She can use an Action List builder to set the value of the processInlineAutoCancel event and display a new page using a Page builder. C. She can use an HTML Event builder to capture the processInlineAutoCancel event of the field and Link To an Action that will display a popup. D. She can use an Event Handler builder to capture the OnRequestComplete event and display a model using the Dojo Dialog builder.
