How to throw the error message after validation?

[Former Member]

Hi Gurus,

I have a requirement where in which drop down field has six values (which is populated from R/3 using adaptive RFC).

Now user wants to block the last three fields (not hide) so that User can see the fields in the drop down but they cannot amend the field as their choice .

Now I have noted the index value of the subjected codes which needs to be in display state.

Index are 3,4,5

So I have written the code if (index =3 || index = 4 || index =5){

I have raise the error message says that " you cannot amend this code"

}

Can you guys please provide the code for the above requirement.

I will surely award higher points for the valuable inputs

Thanks in Advance,

hi,

just see if it helps

if((i ==3) || (i ==4) || (i ==5))

{

wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess("message",true);

}

hi,

first create a mesage of error type in message pool of the component , say Error1-"not allowed to select this option"

after:// begin others

IWDmessageManager msg = null;

//end

now on selectevent:

{

msg = wdComponentAPI.getComponent.getMessageManager();

String value = wdContext.currentDropKeyElement().getKey();

if(value.equals("3") || value.equals("4") || value.equals("5"))

{

//now, raise error Error1.

msg.raiseMessage(IMessageComp.Message id, new Object []{""}, true);

}

Hi Dharani,

In the Message Pool create a new message key and the message, then use the reportMessage() of the MessageManager.

In the Message Pool enter the message which u need to display.

wdComponentAPI().getMessageManager.reportMessage(I<MessageControllerName>.<Message Key>,null,true);

Hope this helps u

hi,

You can use the following code. It has worked for me :

//here you get the ket value

String value = wdContext.currentDropKeyElement().getKey();

if(value.equals("3") || value.equals("4") || value.equals("5"))

{

raise message

}

Hi,

Use

ndex == 3 || index == 4 || index == 5)
		  wdComponentAPI.getMessageManager().reportException("you cannot amend this code");

Other methods which might of interest for you are
reportWarning(String message)
reportSuccess(String message)

Hi Gurus,

Thanx for the input.

when I put this code it throws an error in reportException("you cannot amend this code");

what will be the root cause of this?

please refer the code below

int index12 = wdContext.nodeT505N().getLeadSelection();

if (index12 ==3 || index12 == 4 || index12 == 5) {

wdComponentAPI.getMessageManager().reportException("You cannot amend this code");

}

Thanks in Advance,

Hi,

I think you are using nw04s

use the following function

reportException(message, cancelNavigation)

int index12 = wdContext.nodeT505N().getLeadSelection();
if (index12 ==3 || index12 == 4 || index12 == 5) {

wdComponentAPI.getMessageManager().reportException("You cannot amend this code",true);
}

Hi Aiyapparaj,

Thanks for the valuable input.

Once I chose the index 3 or 4 or 5 it throws the error that i have specified in the code.

But still it allows be to update with the code(3or 4or 5).

My requirement is that user cannot proceed further if they amend this code(3or4or5).

Only they can proceed if they change the code .

How to restrict that?

Please provide the solution for that

Thanks in Advance,

Hi,

Make use of the following function

reportContextAttributeMessage(IWDNodeElement element,

IWDAttributeInfo attribute, IWDMessage messageItem, Object[] args,

boolean cancelNavigation

Hi Aiyapparaj,

I had put the code after the below code,Ihave created in the message pooland the message key is NoAmend

but it throwing the error message in "element"

Since am new to java webdynpro I don't understand this?

Can you expalin in detail how to implement this scenario

int indx = wdContext.nodeT505N().getLeadSelection();

if (indx == 3 || indx == 4 || indx == 5) {

reportContextAttributeMessage(IWDNodeElement element,

IWDAttributeInfo attribute, IWDMessage messageItem, Object[] args,

boolean cancelNavigation

Looking forward to hear from you soon.

Thanks in Advance,

Hi Aiyapparaj,

I have done this way but it throws the below error.

Please refer the code followed by error.

wdContext.nodeT505N().setLeadSelection(index);

int indx = wdContext.nodeT505N().getLeadSelection();

if (indx == 3 || indx == 4 || indx == 5) {

IWDAttributeInfo attributeInfo = (wdContext.nodeT505N().getNodeInfo().getAttribute("indx"));

msgMgr.reportContextAttributeMessage(wdContext.currentT505NElement(),attributeInfo,IMessageEnfDisability.NO_AMEND,

null,true);

Error details:

java.lang.IllegalArgumentException: The node, node element, and attribute info MUST NOT be null

Hi Dharani,

I think u r trying to use reportContextAttributeMessage() for which the parameters are wrong.

try using the reportMessage(I<MessageCompName>.messagekey,null,true);

[former_member751941]

Hi Dharani,

Try this.

int n = wdContext.nodeT505N().size();

int index12 = wdContext.nodeT505N().getLeadSelection();

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

if (index12 ==3 || index12 == 4 || index12 == 5) {

wdComponentAPI.getMessageManager().reportException("You cannot proceed with this codes",true);

break;

}

else

{

// put the code if charge code is different.

}

}

To use the message from the message pool. Use reportMessage method as Poojith says.

HI,

You can check for the index value like this:

//write this code in the OnSelect action of your dropdown

int selectedidx = wdContext.node<nodename>().getLeadSelection();

if(selectedidx==3 || selectedidx==4 || selectedidx==5)

{

wdComponentAPI.getMessageManager().reportError("you cannot ammend this field");

}
