Through sightly I printed a list of textarea values entered via dialog as follows:

<p> Comments: ${commento.testo}</p> "Testo" is the value in the dialog inside the textarea. In the model instead I inserted the testo variable, getter and setter and the "modifyText" method. Now, without creating a list in the model, I would like to print these modified values using sightly

@vodjakxa :
In sling model

@Model(adaptables = SlingHttpServletRequest.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public class ModelClass {

    @RequestAttribute
    private String value;

   public List<String> getListChildren(){
    // create list of values based on dialog values;
    return listofValues;
   }

    public String getModifiedValue(){
     return modifyOriginalValue(value);
    }
   private String modifyOriginalValue(String val){
    //custom logic to modify the value;
    String modifiedVal = val + "some random text";
    return modifiedVal;
  }
}

In Sightly, please try with something like this.

<!-- list item value>

${item}

<!-- modified item value>

${commenti.modifiedValue @value=item}

</sly>

The code I wrote is to print a list of values entered from the dialog. I would then like to print these same modified values via a simple method I have in the sling model, but without creating a list in the model. I would like to always print using sightly. Thanks!
