Table column Total

25 Views

Hi,

I am trying to implement utility class(Calculating total for 1 column) in my application.

I have 2 views and one custom controller.

1) TableUtilities.java class imported to src/packages.

2) Created a value attribute say tableutility in ResultView Context ,and assigned the properties of the attribute type Java Native Type "TableUtilities".

Do I need to create anything other than this?.

Below code is added to the ResultView wdDoModifyView

-

if(firstTime) {

IWDTextView tv = (IWDTextView)view.getElement("total");

wdContext.currentContextElement().setTableutility(new TableUtilities(wdContext.nodeDepartments()));

//Returns attribute info of a dynamically created attribute which can be bound to the UI element need.

tv.bindText(wdContext.currentContextElement().getTableutility().CalculateSum("Departments","NoOfPeople"));

}

If I implement this code in my Resultview wdDoModifyView, it is throwing run time errors.........
