Reg: Message Pool

[Former Member]

Hi All,

Can anybody tell me about Message Pool. How can we use Message pool for validations. Actually when we are working on tutorial 3 error messages Application. I am unable to understand the code in that tutorial. Please help me on that.

Thanks

For validation..

public boolean CheckValidation( )

{

//@@begin CheckValidation()

IWDMessageManager msg=wdComponentAPI.getMessageManager();

String value=wdContext.nodePassenger().currentPassengerElement().getAttributeAsText("NAME");

int value1=wdContext.nodePassenger().currentPassengerElement().getAGE();

String value2=wdContext.nodePassenger().currentPassengerElement().getAttributeAsText("GENDER");

if(value.length()==0)

{

msg.reportMessage(IMessageFlightComp.MISSINGNAME,new Object[]{"NAME"},false);

return false;

}

else

{

String name = wdContext.nodePassenger().currentPassengerElement().getNAME();

int i,len = name.length();

for(i=0;i<len;i++)

{

if(!((name.charAt(i)<=90 && name.charAt(i)>=65) || (name.charAt(i)<=122 && name.charAt(i)>=97) || name.charAt(i)==32 || name.charAt(i)==46))

{

msg.reportMessage(IMessageFlightComp.NAME_ALPHABETS,new Object[]{"NAME"},false);

return false;

}

}

Hi Kodalivenu,

The Message Pool is mainly used for internationalization.Look here to understand the purpose you'll require to open the Message Pool and try creating a message within it.Now the dialog box that appears will ask you for the message text type and there'll be a checkbox checked for translatable.This I guess clarifies the

relevance.Now for understanding the code:

IWDMessageManager msgMan = wdComponentAPI.getMessageManager();
    msgMan.reportMessage(msgItem,null,false);
// here you'll have msgItem = which is the Message Key of the Message Created.
/// null = represents an object argument which Object[].
/// boolean value represents the navigation =  ... If you have to cancel navigation the basis of the Message ... pass true

Now there is another way of accessing the Messages and that is through the text

accessor take a look at the following code:

IWDTextAccessor textAccessor = wdThis.wdGetAPI().getComponent().getTextAccessor();
		textAccessor.getText(String MessageKey);

I think the code is self explanatory.

Hai,

You can create no.of messages in a pool in key value type format

eg:

key type value

Missing Input error Please Enter . here means avariable, when you call this message you need to send this variable, like you can send any variable to message ,,,.... below code is to get the message manager IWDMessageManager msgMgr = wdComponentAPI.getMessageManager(); now you are reporting an exception to an attribute IMessageSimpleErrors.MISSING_INPUT :This Represent an access key for message. new Object[] {"Name"} : you are apssing value to variable, as you defined message pool.

now the message look like Please Enter name (repalced eith name).

msgMgr.reportContextAttributeMessage(

wdContext.currentContextElement(), attributeInfo, IMessageSimpleErrors.MISSING_INPUT, new Object[] {"Name"},

true);

Hi ,

Here is a sample code to know how to use message pool in validation.

public boolean CheckValidation( )

{

//@@begin CheckValidation()

IWDMessageManager msg=wdComponentAPI.getMessageManager();

String name=wdContext.nodePassenger().currentPassengerElement().getAttributeAsText("NAME");

if(name.length()==0)

{

msg.reportMessage(IMessageFlightComp.MISSINGNAME,new Object[]{"NAME"},false);

return false;

}

else

{

return true;

}

}

Here MISSINGNAME is the message Key, with message type 'error' , and message text "Please enter Name"...

And NAME is the context Element...

Hope it will help you...

Satish,

why dont you try

<a href="http://help.sap.com/saphelp_erp2005/helpdata/en/36/d4528e6dbf084b9d79a50fb8d08e86/content.htm">http://help.sap.com/saphelp_erp2005/helpdata/en/36/d4528e6dbf084b9d79a50fb8d08e86/content.htm</a>

Hi Kesari,

What Sathish did is correct.

If all are pasting the links as you said above, it would be a double work for every user. If there is massive data, in that link then you can paste the link...

Thanks and Regards,

Hi Satish,

I am no controller of this forum.Niether do I want to make such posts.What I meant of the post is that one should rather write his/her own experience rather paste some help.sap.com link or data .The assumption over here that others dont have access to help.sap.com is not required.Preserve your post for something you want to share which you have experienced rather than posting help.sap links or data which does'nt make any sense over here with a particular.I dont get the concept in this case of what you are trying to achieve because this is a forum and if you dont have anything original or pertaining to your experience to say.There'll be others who will be definitely help. So dont be so desperate to help that you start posting help.sap data directly and

also

If I take ur point that you gave in you previous post lets see what you did :

If you look at the first link which also comes from the help.sap.com compare the size of content you have pasted to the size of the information on the page ;).

maybe that will clear your own doubt 😊

Happens sometime.Dont worry I am cool man!

Regards

Amit

Hi kesari..

Ok fine.But, Hereafter Don give your personal opinions in others thread. Try to avoid tht. Bcz forum is only for sharing our experiences and helping to others. Dont Interfare and disturb others by giving opinions..

Now I will give you my opinion which happens to also be part of the guidelines of this community.

1) Keep the conversation cordial no ATTACKS.

2) If a user is asking something and the answer is right there in help.sap.com which EVERYONE has access then post the link is the right way to go.

If every user jumps in (and I see multiple cases right here in this thread) and adds their thoughts then why should a user ever have to actually search and do a bit of research (and thus learn) on their own. This is not a place of "quick answers" but rather a place to interact with your peers and learn from one another not to simply get the answer and be done with it.

So if the answer is already there "LINK TO IT" don't repost the answer. Users should learn from the example of all of us and "SEARCH FIRST".

The other thing to remeber 90% of experience is opinion, it's your interpretation of "how it's supposed to be"
