@lokesh_vajrala Since we are using 

defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL

there is no need to check  

if (StringUtils.isNotBlank(textfieldA)) {
            return textfieldA;
        }

HTL Engine evaluates it internally.

Hi @sasi1,

I would manage this with the implementation of Sling Model, Kindly refer below code.

Sling Model

@Model(adaptables = Resource.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL) 
public class DemoModel { 
      @Inject private String textfieldA; 
      @Inject private String textfieldB;

public String getTextfieldA() { returntextfieldA; }

public String getTextfieldB() { returntextfieldB; } 
}

HTL

<sly data-sly use.model="com.models.DemoModel" />
      <div>${model.textfieldA}></div>
      <div data-sly-test="${!model.textfieldA}">${model.textfieldB}></div>

or you can use HTL directly as below

<div>
      <div>${properties.textfieldA}></div>
      <div data-sly-test="${!properties.textfieldA}">${properties.textfieldB}></div>
</div>

Hope that helps!

Regards,

Santosh

    Slightly better version - handle the logic in the Sling Model and return text value to render through HTL, so you will not see empty <div> elements in the generated markup.

    @Model(adaptables = Resource.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public class DemoModel {
    @Inject 
    private String textfieldA;
    @Inject 
    private String textfieldB;

    public String getText() {
        // textfieldA is not null and not empty, return textfieldA and don't look for textfieldB value
        if (StringUtils.isNotBlank(textfieldA)) {
            return textfieldA;
        }
        // textfieldA is either null or empty, return textfieldB value if it is not null and not empty
        if (StringUtils.isNotBlank(textfieldB)) {
            return textfieldB;
        }
        return null;
    }
}

    HTL 

    <sly data-sly use.model="com.models.DemoModel" />
<div data-sly-test="${model.text}">${model.text}></div>
