How to implement paging in webdynpro jave based on search criteria.

Question

Hi All,
In a requirement I need to implement paging in webdynpro java development.
I successfully did it when there is no search criteria is available i.e webdynpro fetched all data from the BO object and I did it using a "indexNO" (unique serial no from 1,2,3,4.....) field available in BO object.
But when there is search criteria available , i.e the data to be fetched from the BO based on some specific field , at that time the "indexNo"  field of all data fetched based on search criteria are discrete i.e not continious. In that case how to implement the paging concept.
I am using CE version 7.1 EHP 1.
Thanks in advance

Hi,
If you go to your VO and generate the ViewObjectImpl, in there you can create a method which will contain two parameters, 1 the attribute name and 2 the value.
Then you can follow something like explained in this post:
ADF Tutorial: How to apply bulk actions to a view object rows
The only difference is that you will need to create a method like this:
public void updateAttribute(String attribute, Integer value){
        RowSetIterator iter = createRowSetIterator(null);
        while (iter.hasNext()){
            Row row = iter.next();
            row.setAttribute(attribute, value);
Then you expose that as a client interface and then after you filter your table by your criteria you just need to execute this method passing the right parameters.
