How Dynamically control text property of LinkToUrl

[Former Member]

Hi,

My requirement is I am fetching emai id records from

SAP/R3 and displaying in table.In table one field is

Email Id.When I am click on email id Microsoft outlook express is opening and the mail id is automatically comming to the To field of outlook express,because before binding to reference property of LinkToUrl I modified in Component context code like mailto:xyz@yahoo.com.I set reference and

text property of LinkToUrl to <context node>.<node value>.My problem is in reference and text property of LinkTOUrl mailto:xyz@yahoo.com is comming.I want in text property xyz@yahoo.com and in reference property mailto:xyz@yahoo.com should be come

Thanks & Regards

Hi,

According to Armin suggesion I created calculated

attribut(first i created one value attribute in name of calculate and set calculated property to true and ser read only to true)in context of component controller.

I added following code in getter method .

public java.lang.String getOutputCalculate(IPrivateBirthDayAppCust.IOutputElement element)

{

//@@begin getOutputCalculate(IPrivateBirthDayAppCust.IOutputElement)

return element.getAttributeAsText("BirthDayAppModel.Zbirthday_List.Email_Id");

//@@end

}

Under Outputput model node I created calculate value attribute.My component Context node structure is like

this.

Context->OutPut(Model Node)->Birthdaylist(Model Node)->Email_Id (Model Attribute).

I am mapping Component Context to View context(Result View).My view context Structure is like.

Context->Birthday(Model Node)->Birthdaylist(Model Node)->

Email_Id.calculate attribute created under Birthday.

when i am running application i got nullpointer exception.

The initial exception that caused the request to fail, was:

java.lang.NullPointerException

hi

Make it calculate true context node attributes properties.

Then automatically created getter and settermethod will be generated u can write the code inside the methods.

When make it true method structures are created inside view.

Thanks

Hi

In the Component controler youcan see the property of the Element calculated false/true.

you can set as true and you can see the methods as

calculatedAttributeGetter <getTest>

calculatedAttributeSetter <setTest>

you can do the calculated values in this part

See this blogs

Create context attribute and set "calculated" = true and "readOnly" = true in the property editor.

Hi,

you need two separate values attributes in your context - one to bind it to text property of LinkToUrl and one to bind it to the reference property.

And you only add "mailto:" to that value attribute, which is bound to the reference property.

Create calculated attribute "MailToURL" and implement getter like

String getMailToURL(I<Node>Element element)
{
  return "mailto:" + element.get<attribute-storing-text>();
}

Bind LinkToURL.<i>reference </i>property to attribute "MailToURL".
