clear data

i need to clear the data

wdDoModify(){

//create and populate data in table inside IWDTransparentContainer

}

first time page1, when i key in the value for instance

customer id : 00001

the page will naviagate to page2

and populate the data in the table correctly,

later , if i naviagate back to page 1 and key in different values,

the data still the same,

i submit the data to call a model with the value in input field...

the data doesnt refresh....in wdDoModify...

Hi Yzme,

You can place the code to clear the "inputfield" in the "onPlugfrom<Page2>"

method in ur Page1 (View 1) instead of wdoModifyview().

Hope it helps.

Alka.

inputfield value is not an issue, the data it get back is.

the thing is the data get populated the first time i key in the value

for instance 000001

2nd time : 000002

the data inside same as the first time. but i am sure that i pass in 00002 into the function..

the data is get populated inside the wdModifyView..

HI,

Make sure that u added wdContext.nodeOutput().invalidate()

after calling RFC inside execute().

If this is not the issue, then u can invalidate the node of the WebDynpro table by

wdContext.node<Table>().invalidate();

inside the inbound plug to which the 2nd view returns.

Regards

something like this

but what is the solution

it reflect the changes in the table with the bindings

the data populated in the table reflect the changes

NodeOutput

- NodeOutputCalendar

- NodeOutputEmployee

- NodeOutputLeave

if i bind the those node in each tables, it reflect the changes

after i invalidate()

but when i create the table dynamically ,where i combine several nodes to create the table

wdDoModify(){

IWDTransparentContainer rootElement;

if(firstTime()){

System.err.println("break point 1");

rootElement=(IWDTransparentContainer)view.getElement("TransparentContainer_Calendar");

System.err.println("break point 2");

}

View 1 to View 2--input : 00001 View 2 refect changes and the table successfully created dynamically.

after that navigate back : Enter input : 00002 and the 00002 is pass in correctly to the function, the table in the binding works ok. but not the table create dynamically.

it only show break point 1 and will not get into break point 2


rootElement=(IWDTransparentContainer)view.getElement("TransparentContainer_Calendar");
IWDNodeInfo tabNode=wdContext.getNodeInfo().addChild("Tab_Node",null,true,true,true,false,true,false,null,null,null);
IWDTable tab=(IWDTable)view.createElement(IWDTable.class,"Dyntable");
IWDNode dynTabNode=(IWDNode)wdContext.getChildNode("Tab_Node",0);

if i remove the

if(firstTime){

}

i will receive this

Exception wdDoModify: DataNodeInfo(TeamCalendarView): duplicate name for child node Tab_Node


if (firstTime) {
		
		  IWDTreeNodeType treeNode = (IWDTreeNodeType) view.getElement("TheNode");

Something amiss here !

Change the view property LifeSpan to "When Visible" and run the application.

Thanks and Regards

Hi,

You just use the invalidate() method to refresh the node values.for example if ur table node is "NODE" then u write code like below.

wdContext.nodeNODE().invalidate();
