Validate form field for CE 7.1 SP3

24 Views

Hi Experts

I want to validate the form field and I follow the example of the SimpleError Form sample:

public void checkMandatory(java.lang.String fieldName) {

//@@begin checkMandatory()

IWDMessageManager messageMgr =

wdComponentAPI.getMessageManager();

Object attributeValue =

wdContext.currentContextElement().getAttributeValue(fieldName);

IWDAttributeInfo attributeInfo =

wdContext.getNodeInfo().getAttribute(fieldName);

if (attributeValue instanceof String) {

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

String fieldLabel =

wdContext.getNodeInfo().getAttribute(fieldName)

.getSimpleType().getFieldLabel();

messageMgr.reportContextAttributeMessage(

wdContext.currentContextElement(),

attributeInfo,

IMessageSimpleErrors.MISSING_INPUT,

new Object[] { fieldLabel },

true);

}

//@@end

}

...

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

{

//@@begin onActionSave(ServerEvent)

this.checkMandatory(IPrivateForm.IContextElement.NAME);

this.checkDateInPast(IPrivateForm.IContextElement.BIRTHDAY);

this.checkDesired(IPrivateForm.IContextElement.E_MAIL_ADDRESS);

wdComponentAPI.getMessageManager().raisePendingException();

wdComponentAPI.getMessageManager().reportSuccess(

"The sample form data was successfully saved!");

}

However, I realise that some of the methods used in the sample are already depreciated. Methods such as reportContextAttributeMessage and raisePendingException();

I am currently using CE7.1 SP3

Can advise ?

Thank you.
