Table Sorting

[Former Member]

hi

iam performing table sorting on the model node

and first table its working fine , but when iam trying to sort

the second table its throwing null pointer exception

in the action method .

if(firstTime)

{

view.nowCreateAllCustomExtensionFields();

IWDTable tab= (IWDTable)view.getElement("tbl_car");

IWDTable tabCarv=(IWDTable)view.getElement("tbl_carv");

wdContext.currentContextElement().setCarTableSorter(new TableSorter(tab,wdThis.wdGetCarTableSorterAction(),null));

wdContext.currentContextElement().setCarvTableSorter(new TableSorter(tab,wdThis.wdGetGetTableSorterAction(),null));

}

i have written the above code and then created

two action methods

first action method

wdContext.currentContextElement().getCarTableSorter().sort(wdEvent,wdContext.nodeIt_Car_Data())

second action method

wdContext.currentContextElement().getCarTableSorter().sort(wdEvent,wdContext.nodeIt_Carv_Data());

and two context variable of type TableSorter

is throwing NULL pointer exception for the second table action when iam trying to sort.

can any one help me out ?

In your code you create both table sorter instances for the first table ("tab").

Hi,

Just add the condition as follows:

if(null != wdContext.nodeIt_Carv_Data()) {
         wdContext.currentContextElement().getCarTableSorter().sort(wdEvent,wdContext.nodeIt_Carv_Data());

}

The same thing i did as i got the NPE when there was no data in the node.

Hope this helps.

thanks & regards,

Manoj
