Doubt in Multiselection in a table

Oct 19, 2006 at 12:22 PM | 4 Views

Hi All,

I have a table and have to to multiselection.While doing the multiselection I have to pass the few things for the selected rows to a BAPI which will process and give the output accordingly.

In an action handler I am writing the following code:

//*****Trying the multiselection****//

IOPENITEMS_openElement tableEle = null;

IPrivateCreateResultIPView.IMultiNodeElement ele = wdContext.nodeMultiNode().createMultiNodeElement();

for(int i=0;i<wdContext.nodeOPENITEMS_open().size();i++){

wdComponentAPI.getMessageManager().reportSuccess(" Size is :"+wdContext.nodeOPENITEMS_open().size());

boolean aa = wdContext.nodeOPENITEMS_open().isMultiSelected(i);

wdComponentAPI.getMessageManager().reportSuccess("Selected : "+i " : Val "aa);

if(aa){

wdComponentAPI.getMessageManager().reportSuccess(" Selected "+i);

tableEle = (IOPENITEMS_openElement)wdContext.nodeOPENITEMS_open().getElementAt(i);

ele.setMultiDocno(tableEle.getDOC_NO());

ele.setMultiItem(tableEle.getITEM());

ele.setMultiRep(tableEle.getREP_ITEM());

ele.setMultiSub(tableEle.getSUB_ITEM());

wdContext.nodeMultiNode().addElement(ele);

}

}

//****Ends here***//

here multiNode is a local View node that I have taken to collect the records or the data for the selected rows.

The Exception that i am getting

com.sap.tc.webdynpro.progmodel.context.ContextException: Node(CreateResultIPView.multiNode): cannot bind or add element, because it is already bound to a node

at com.sap.tc.webdynpro.progmodel.context.Node.prepareAddElement(Node.java:645)

at com.sap.tc.webdynpro.progmodel.context.Node.addElement(Node.java:631)

at com.accenture.pct.rrs.installmentplan.CreateResultIPView.onActionCreateInstallmentPlan(CreateResultIPView.java:462)

at com.accenture.pct.rrs.installmentplan.wdp.InternalCreateResultIPView.wdInvokeEventHandler(InternalCreateResultIPView.java:1597)

at com.sap.tc.webdynpro.progmodel.generation.DelegatingView.invokeEventHandler(DelegatingView.java:87)

Kindly give a solution to the problem.I have been struggling for the past one whole day.

looking forward to you.

Regards

    Hi DK,

    It is simple. Bring that element into the for loop.like,

    IPrivateCreateResultIPView.IMultiNodeElement ele = null;

    for(int i=0;i<wdContext.nodeOPENITEMS_open().size();i++){

    ele = wdContext.nodeMultiNode().createMultiNodeElement();

    //write your logic here

    wdContext.nodeMultiNode().addElement(ele);

    }

    Hope it solved ur problem.Otherwise get back.

    Regards,

    SK

      Hi SK,

      Thanx for the reply..its working without any exception..but even after taking a node..still it is taking only the lastrecord..

      I dont understand what is the other approach..

      Let me know if you have any solutions.

      Regards

      DK

    Try this

        int n = wdContext.nodeOPENITEMS_open().size();
    wdComponentAPI.getMessageManager().reportSuccess("Size of node OPENITEMS_open: " + n);
    for (int i = 0; i < n; i++)
    {
      boolean selected = wdContext.nodeOPENITEMS_open().isMultiSelected(i) || wdContext.nodeOPENITEMS_open().getLeadSelection() == i;
      if (selected)
      {
        wdComponentAPI.getMessageManager().reportSuccess("Element at index " + i + " is selected");
        IOPENITEMS_openElement src = wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(i);
        IMultiNodeElement tgt = wdContext.nodeMultiNode().createMultiNodeElement();
        wdContext.nodeMultiNode().addElement(tgt);
        tgt.setMultiDocno(src.getDOC_NO());
        tgt.setMultiItem(src.getITEM());
        tgt.setMultiRep(src.getREP_ITEM());
        tgt.setMultiSub(src.getSUB_ITEM());
      }
    }
