Doubt on Drop Down box by key

[Former Member]

Hi All,

My requirement is to fill a dropdown with values in accordance to the selected value of another drop down...

My code is as follows..

private void fillTaxTypes(){

IModifiableSimpleValueSet dropTTValueSet;

IWDAttributeInfo addressAttributeInfo = wdContext.getNodeInfo().getAttribute("vaTaxType");

wdComponentAPI.getMessageManager().reportWarning("check here");

dropTTValueSet = addressAttributeInfo.getModifiableSimpleType().getSVServices().getModifiableSimpleValueSet();

//wdComponentAPI.getMessageManager().reportWarning("check there");

int nodeSize = wdContext.nodeCONTRACCOUNTLIST_new().size();

dropTTValueSet.clear();

dropTTValueSet.put("0","Select");

for(int i=0;i<nodeSize;i++){

dropTTValueSet.put(wdContext.nodeCONTRACCOUNTLIST_new().getElementAt(i).getAttributeAsText("cONT_ACCT"),wdContext.nodeCONTRACCOUNTLIST_new().getElementAt(i).getAttributeAsText("cONT_ACCT"));

}

I am calling the method in an action.(event handler)

But I am getting an error...

Kindly suggest me...

Regards

DK

DK,

I guess your problem is with the Variable Type.

Use your view local context variable in the below code.

IWDAttributeInfo addressAttributeInfo = wdContext.getNodeInfo().getAttribute("vaTaxType");

(Or) get the Custom controller / Component Controller context attribute info like this.

IWDAttributeInfo iAttInfo = wdThis.wdGetWelcomeComponentController().wdGetContext().getNodeInfo().getAttribute("vaTaxType");

Hopefully, your problem might have solved.

Hi,

Can you let me know the error you got?

And also is the <b>nodeCONTRACCOUNTLIST_new</b> getting data from a backend?
