hi Suresh,

Please check selection cardinality for the context node.

I t should be 0..1 or 0..n.

If it is 1..1 or 1..n leadselection gets automatically initialized.

also check if initializeLeadSelection= false set for the context node.

Hope this helps!

Hi,

If you want to keep blank vlaues in drop drop down when you click new action you can do this.

Whichever node you have maped to dropdownbyindex make that node as invalidate();

eg

wdcontext.nodedropdown().invalidate();

keep this line in onactionNew();

Hi

In the wdDoInit() method of view write the following code:

wdcontext.node<nodename>.setleadselection(-1);//Node name is the context node to which drop down is mapped.

Thanks

HI,

When i select row in the table the record will appear one screen,here we can edit and save.After screen appear with out doing anything clikcing on back button and then NEW button the dropdown is not showing blank.

Try this, onAction Back, set the lead selection of ur node to -1.(here node drop is bound to drop down)

wdContext.nodeDrop().setLeadSelection(-1); so when u click new Button, the drop down will remain blank.

Thanks and Regards

HI Fazal,

I had done this already but its not working.When wdcontext.nodexxxx.invalidating is not using in code then it was working

but if i am invalidating then it was not working.With out invalidating the dropdown willnot refresh.

Can you please give your inputs.

Without knowing the context structure and how the controllers are related it is difficult to answer what you are doing wrong.

HI Armin,

I had created one valuenode in custom controller in custcontroller.I had used this valunode in both the views using contest mapping.

After i had binded the valueattribute to dropdown from that value node.

In the first screen i have table with onlead selection and in second screen i.e click on NEW and onleadselection in the table that is the second screen both screens are same.

Now i wrote entire logic in fireplugfromfirstscreen action,so when i click on NEW and onlead in table then the entire logic will implement.

Intally when i entered into firstscreen and directly clicking on NEW button then dropdown showing blank but when i click on

leadselection and nothing doing and click on another back button and again NEW button,here the dropdown is not showing blank.Here its showing first elemnt in dropdown

I am unble to find error.

I had set valuenode to -1 (wdcontext.valuenode().setleadselection(-1)) in NEW button and fireplugfromfirstscreen and onaction BACK but its not working.

Your question is unclear to me. Say you have the following context structure:

Rows (node, c=0:n)
+ Items (node, c=0:n, s=0:1, singleton=false)
   + text (string)

Node "Rows" represents the table rows, "Items" represents the items in the drop-down lists in each row.

To clear the selection of the drop-down list at row #i you need to clear the lead-selection of the corresponding "Items" node:

IRowsElement row = wdContext.nodeRows().getRowsElementAt(i);
row.nodeItems().setLeadSelection(IWDNode.NO_SELECTION);

Hi Suresh

Set intialLeadSelection = false for the table node

and selection cardinality to 1:1

hope it will work

Thanks
