Mandatory check problem

[Former Member]

Hi everyone,

I have some code to check if the mandatory inputfield is filled by the user:

public void CheckMandatory( java.lang.String fieldname )

{

//@@begin CheckMandatory()

IWDMessageManager messageMgr = this.wdThis.wdGetAPI().getComponent().getMessageManager();

Object attributeValue = this.wdContext.currentContextElement().getAttributeValue(fieldname);

IWDAttributeInfo attributeInfo = this.wdContext.getNodeInfo().getAttribute(fieldname);

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

messageMgr.reportContextAttributeMessage(wdContext.currentContextElement(),attributeInfo,IMessageBasics_Error.MISSING_INPUT,new Object[] { fieldname },true);

}

//@@end

}

but when we excute the code to "if (((String) attributeValue).length() == 0)",dump window appears.I debugged into the code and found the "attibuteValue" is not an empty string but an null value,maybe that's the reason for the dump.

How to deal with the problem? Thanks in advance.

Hi,

Take the value as string

Instaed of this

Object attributeValue = this.wdContext.currentContextElement().getAttributeValue(fieldname);

put this

String value ="";

value = this.wdContext.currentContextElement().getAttributeAsText(fieldname);

Then check for this condition

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

messageMgr.reportContextAttributeMessage(wdContext.currentContextElement(),attributeInfo,IMessageBasics_Error.MISSING_INPUT,new Object[] { fieldname },true);

}

Hi Begue,

Implement Chandran's method for validation.

Using the Required property will not help, if the fieldValue, is a String type Context.

Coz, NULL is a valid value for String Object.

Hi ,

Instead of writing code,

you can select the state property of Inputfield as required.

I think this will do..

Hi,

Try this

if ( null == attrributeValue || attributeValue.trim().length() == 0)){

messageMgr.reportContextAttributeMessage(wdContext.currentContextElement(),attributeInfo,IMessageBasics_Error.MISSING_INPUT,new Object[] { fieldname },true);

}

//@@end

}

Hi ,

Try this way

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) {

messageMgr.reportContextAttributeMessage(

wdContext.currentContextElement(),

attributeInfo,

IMessageRequisitionForm.MISSING_INPUT,

new Object[] { fieldLabel },

true);

}

} else if (attributeValue instanceof Integer) {

}

Hi

Make use of this code

Object attrValue = wdContext.currentContextElement().getName();
 if(attrValue==null)
 {
    wdComponentAPI.getMessageManager().reportSuccess("The Value is Null");
 }
 else
 {
     wdComponentAPI.getMessageManager().reportSuccess("Entered  Value"+wdContext.currentContextElement().getName());
  }

Regards
