Getting Error: java.lang.IllegalArgumentException: can't parse argument 0

[dhruv_shah3]

HI All,

I am implementing the Message Pool in NWDS.

I have two InputFields: Firstname and Lastname.

and i have a method name: CheckMandatory which takes one argument as String.

I have implemented this Method in the StartView. Now when i am leaving this fields empty and pressing the Go Button.

Then i am getting the Following Error:

java.lang.IllegalArgumentException: can't parse argument number 0

So pls help me out......

Hi,

I made some changes in this code ,pls try this as it is

IWDMessageManager mess = wdComponentAPI.getMessageManager();

Object value = <b><b>wdContext.currentPersonElement().getAttributeAsText(FieldName);</b></b>

IWDAttributeInfo attr = wdContext.nodePerson().getNodeInfo().getAttribute(FieldName);

//if (((String)value).length() == 0)

if(wdContext.currentPersonElement().getName() == null)

{

mess.reportContextAttributeMessage

(<b>wdContext.currentPersonElement(),</b>

attr,IMessageWelcome.MISSING_INPUT,new Object[] {Fieldlable},

true);

}

I tested its working for me..

Hi Sumit,

I have the Following Code:

I have following Code in CheckMandatory method:

public void checkMandatory( java.lang.String fieldname, java.lang.String fieldlabel )

{

//@@begin checkMandatory()

IWDMessageManager mess = wdComponentAPI.getMessageManager();

Object value = wdContext.nodePerson().currentPersonElement().getAttributeAsText(fieldname);

IWDAttributeInfo attr = wdContext.nodePerson().getNodeInfo().getAttribute(fieldname);

if (((String)value).length() == 0)

{

mess.reportContextAttributeMessage

(wdContext.nodePerson().currentPersonElement(),

attr,IMessageStart.MISSING_INPUT,new Object[] {fieldlabel},

true);

}

//@@end

}

And in ActionGo i have following Code:

public void onActionGo(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

{

//@@begin onActionGo(ServerEvent)

//$$begin ActionButton(-1139129802)

this.checkMandatory(IPrivateStartView.IPersonElement.FIRST__NAME,"FIRST_NAME_label");

this.checkMandatory(IPrivateStartView.IPersonElement.LAST__NAME,"LAST_NAME_label");

wdComponentAPI.getMessageManager().raisePendingException();

wdThis.wdFirePlugToMainView();

//$$end

//@@end

}

And i am getting the Error:

java.lang.IllegalArgumentException: can't parse argument 0

Hi Dhruv,

In ur code ,nowhere u r checking for null values.when first name is not available, the attribute contains null.

so use this

if (((String)value).length() == 0 || nul l== ((String)value))

{

mess.reportContextAttributeMessage

(wdContext.nodePerson().currentPersonElement(),

attr,IMessageStart.MISSING_INPUT,new Object[] {fieldlabel},

true);

}

Hi,

Try this condition

if (((String)value).length() == 0 || null== ((String)value))

Hi,

Use this code in checkmandatory method

IWDMessageManager messageMgr = wdComponentAPI.getMessageManager();

Object attributeValue =wdContext.currentdetElement().getAttributeValue (fieldName);

IWDAttributeInfo attributeInfo =

wdContext.nodedet().getNodeInfo().getAttribute(fieldName);

if (((String) attributeValue).length() == 0) {

messageMgr.reportContextAttributeMessage( wdContext.currentedetElement(),

attributeInfo,

IMessageForm.MISSING_INPUT,

new Object[] { fieldLabel },

true);

}

} else if (attributeValue instanceof Integer) {

}

call that mandatory in the Go action as:

this.checkMandatory( IPrivate<>View.detailElement.<fieldname>,

"labelname");

Then raise pending exception.

It will work

karthik.

Hi,

Change the code

if (((String)value).length() == 0)

to

String.valueOf(value).length()

can you update the post with the entire stack trace
