Enum defaults are not filled in form

activista

Hello Activity Forum,

I am just wondering if this is with purpose, but with form properties for the enum type default value are not automatically filled.
If not purposeful, can this be corrected?

A.

Can you give an example of that? It's a long time ago since we wrote those enum form properties 😉

How you define the default value for enum in bpmn20.xml file?

This is how it is done as the result of the Eclipse Designer; refer to line activiti:formProperty id="examtype":
….
      <extensionElements>
        <activiti:formProperty id="examtype" name="Exam type" type="enum" default="h">
          <activiti:value id="m" name="Maths"></activiti:value>
          <activiti:value id="l" name="Literature"></activiti:value>
          <activiti:value id="h" name="History"></activiti:value>
        </activiti:formProperty>
      </extensionElements>
    </userTask>

The default="h" value is just ignored intoorg.activiti.explorer.ui.form.EnumFormPropertyRenderer of A.E: 5.10 and A.E 5.11 :geek:

public class EnumFormPropertyRenderer extends AbstractFormPropertyRenderer {

public EnumFormPropertyRenderer() {
    super(EnumFormType.class);
}

@SuppressWarnings("unchecked")
@Override
public Field getPropertyField(FormProperty formProperty) {
    ComboBox comboBox = new ComboBox(getPropertyLabel(formProperty));
    comboBox.setRequired(formProperty.isRequired());
    comboBox.setRequiredError(getMessage(Messages.FORM_FIELD_REQUIRED, getPropertyLabel(formProperty)));
    comboBox.setEnabled(formProperty.isWritable());

    Map<String, String> values = (Map<String, String>) formProperty.getType().getInformation("values");
    if (values != null) {
      for (Entry<String, String> enumEntry : values.entrySet()) {
        // Add value and label (if any)
        comboBox.addItem(enumEntry.getKey());
        if (enumEntry.getValue() != null) {
          comboBox.setItemCaption(enumEntry.getKey(), enumEntry.getValue());
        }
      }
    }
    return comboBox;
}
}

The org.activiti.engine.form.FormProperty interface has no method, that would be represent the "default" attribute of xml element formProperty :roll:

So what you're saying is that there is a bug in that impl, right? Please create a jira issue so we can follow it up (and link it to this post)

As of today 09/27/2013, this is still an issue. I'm using 5.13.
