how to empty a node under Java Web Dynpro?

[Former Member]

Hello,

I want to empty a node in the controller, I tried several attempts to do so, but no attempt is good.

I would like to know if someone already met this problem? If yes, please give me the solution.

Hi,

If your node is a value node then invalidate() will work.

If your node is a model node then for clearing the node, you have the create object of particular model class and bind it to the context node Or remove elements from the model node.

Hi,

The invalidate() method for node should work to clear the nodes element collection.

else we can set "" to each context attribute in a node.

If your node cardinality is 1..1

wdcontext.current<nodeelement>().setname("");

if your node cardinality is 0..n

for (int i=0;i<wdcontext.node<nodename>().size();i++)

{

wdContext.node<nodename>().get<node>ElementAt(i).setname("");

}

Hi,

I already tested it but this attempt does not work.

for (int i=0;i<wdcontext.node<nodename>().size();i++)

{

wdContext.node<nodename>().get<node>ElementAt(i).setname("");

}

Hi,

To empty the nodes element collection, you can use the code

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