wdEvent.getString()

[Former Member]

Hi

I am trying to get the column id by using

wdEvent.getString(<NameOfColumn>);

But I always get null.

Any idea why?

thank you for your help and regards

Hi,

1. Edit your action and add a new parameter of type int and call it "fromcolum". Check that your event handler is also updated with this new parameter.

2. Add this code to the "wdDoModifyView()":

if (firstTime){

IWDTableColumn column = (IWDTableColumn )view.getElement("<id of the tablecolum UI element>");

column.mappingOfOnAction().addParameter("fromcolum",1);

}

3. In your event handler simply access this parameter to find out which column was clicked.

Thanks

I did exactly as you suggest. Thanks

column.mappingOfOnAction().addParameter("type","type"); //random name

but when i try to run the code

String type = wdEvent.getString("type");

I still get null!

Thank you

If you are working in NW 7.0, you should map the predefined event parameter "col" to an action parameter of type "string". See

http://help.sap.com/javadocs/NW04S/current/wd/com/sap/tc/webdynpro/clientserver/uielib/standard/api/...

In NW >= 7.1 you shouldn't use the "onAction" event anymore.

Hallo Armin

As you mention elsewhere on the forum javadoc does not specify what "name-of-action-parameter" // (type String) " mean.

Just to recapitualte:

On the one hand I have a col name "Type". Its onAction is bound to onActionSort.

On the other hand I have the wdDoModify whee i have the foll code:

if(firstTime)

{

IWDAbstractTableColumn col = (IWDAbstractTableColumn ) view.getElement("Type");

col.mappingofAction.addSourceMapping(IWDAbstractTableColumn.IWDOnAction.COL,

"wdEvent");

IWDTable table = (IWDTable) view.getElement("MyTable");

wdContext.currentContextElement.setTableSorter(new TableSorter(table, wdThis.wdGetSortAction,

null));

}

In addition of course I have onActionsort:

public void onActionSort(wdevent)

{

wdContext.currentContextElemet().getTableSorter().sort("Type", wdContext.myNode(), false);

wdContext.nodemyNode().moveFirst();

}

I put a berakpoint at TableSorter.sort() and interestingly enough the method returns after

ReversibleComperator reversible = (ReversibleComparator) comperatorForColumn.get(column);

because reversible gets null. Any idea??

Thank you!!

As I said, add an action parameter "columnId" (name is arbitrary, but not "wdEvent") of type "string" and map the predefined event parameter to it:

col.mappingOfOnAction().addSourceMapping(
  IWDAbstractTableColumn.IWDOnAction.COL,
  "columnId"
);

Hi Armin

Sorry for the late reply.

Apparently the problem, as always, was the version.

There are two versions of "TableSorter" one is for ECC6 and one for ECC7.

To implement my solution I have been referring to

Bertram Ganz' blog: 'WDTableSorter_NW04s.zipEnhanced Web Dynpro Java TableSorter for SAP '

which can be found here:
