Hi,

You can create a key on your own. You don't strictly need it from the webservice.

Quoting previously submitted code:

valueElement.setId("Key_" + loopIndex);//or whatever you might want to put.

Hi,

You can populate dropdown values from webservice using the following steps. I assume you have idea about custom controller and better you have to use DropdownbyIndex intead of DropdowmByKey.

step1:

Create custom controller.Inside custom controller Bind input value then execute webservice.

step2:

Now you have value node which is returned from web service. After execute web service you can find size using the following code. create value(Role_Output) node and modelnode(Role_result) object using the code.

Step3:

<custom controller name>.IRole_ResultNode modelnode=wdContext.nodeRole_Result();

<custom controller name>.IRole_OutputNode valuenode=wdContext.nodeRole_Output();

valuenode.invalidate();

int size=modelnode.size();

Step4:

After find size using loop fetch values from model node into value node.Asume in this value node contains key and value.

for(int j=0;j<modelnode.size();j++){

<custom controller name>.IRole_ResultElement modelElement=modelnode.getRole_ResultElementAt(j);

<custom controller name>.IRole_OutputElement valueElement=wdContext.createRole_OutputElement();

valueElement.setId(modelElement.getKey());

valueElement.setText(modelElement.getValue());

valuenode.addElement(valueElement);

}

step5:

After that bind this value node(Role_Output) into Component controller. Then Bind value node(Role_Output) from component controller into view.

Step6:

Finally bind dropdown UI Element into Role_Output node's attribute(ID).

Hi Saravanan,

Thanks for your help. I have one more doubt here that i am returning a single field table from WebService like name of the user only so how there is no use of key and value so how can i proceed here or i need to use any other UI element or need to change the code?

Thanks

Hi Ninad,

I put sample as returned key and value from webservice. You need to display user name only means just create one attribute(username) under Value node instead of key and value. Use the following code:

Step4:

After find size using loop fetch values from model node into value node.Asume in this value node contains key and value.

for(int j=0;j<modelnode.size();j++){

<custom controller name>.IRole_ResultElement modelElement=modelnode.getRole_ResultElementAt(j);

<custom controller name>.IRole_OutputElement valueElement=wdContext.createRole_OutputElement();

valueElement.setusername(modelElement.getuername());

valuenode.addElement(valueElement);

}

<b>Valuable answer=point</b>

Hi Ninad,

You Don't need to use another UI Element.

name = wdContext().nodeResult().getName();

valSet.put(name,name);

First Element is Key , the Element is Value (which you can see in DD). You can give both with the same value.

Hi Saravanan

Thanks

Hi,

Put the following code inside component controller. Before you should check size of three internal tables(sender,receiver and doctype).What is the output of webservice?.

for(int j=0;j<modelnode.size();j++){

IPrivate<componentcontrollername>.IRole_ResultElement modelElement=modelnode.getRole_ResultElementAt(j);

IPrivate<componentcontrollername>.IRole_OutputElement valueElement=wdContext.createRole_OutputElement();

valueElement.setusername(modelElement.getuername());

valuenode.addElement(valueElement);

}

Kind Regards,

Hi Saravanan

I am extrimly sorry but i am not getting anything from bellow lines

IPrivate<componentcontrollername>.IRole_OutputElement valueElement=wdContext.createRole_OutputElement();

valueElement.setusername(modelElement.getuername());

valuenode.addElement(valueElement);

I will paste my for-loop please tell me what i have to write next for those 3 lines there

for(int i=0;i < wdContext.nodeSender().size();i++)
{
IPrivateDTCEventSearchView.ISenderElement senderElement = wdContext.nodeSender().getSenderElementAt(i);
}

i am testing for sender internal table which is sent over webservice and its returning one record

but while i print the value for sender size which i checked in for-loop condition its returning me zero so please tell me where is the problem

Thanks

Hi,

Please put the follwoing code. Suppose you bind node(ISender_Output) to dropdown with one attribute(username). You should create ISender_Output in Component controller and bind into view finally bind into dropdown.

IPrivateDTCEventSearchView.IRole_OutputNode valuenode=wdContext.nodeRole_Output();

for(int i=0;i < wdContext.nodeSender().size();i++)

{

IPrivateDTCEventSearchView.ISenderElement senderElement = wdContext.nodeSender().getSenderElementAt(i);

IPrivateDTCEventSearchView.ISender_OutputElement valueElement=wdContext.createRole_OutputElement();

valueElement.setusername(senderElement.getuername());

valuenode.addElement(valueElement);

}

Like you can add remaining dropdown.

Hi Saravanan

where i need to create nodeRole_Output its not used anywhere in my code what is that?

Thanks

Hi,

You create nodeRole_Output node inside component controller, because you didn't use Custom controller. Map nodeRole_Output node into view and bind into dropdown UI Element.
