Adding configuration information to a FormProperty

joaquinb — Tue, 17 Sep 2013 15:11:50 GMT

I need to render (with ZK) a UserTask in an application reading collection of formPropertys.I don't know if it's possible to create a new data type and adding configurations to an instance in a form of this datatype.For example, starting at sample TextAreaFormType i need to configure number of rows

Sorry there is errors in previos text

I need to know if its posibble to add custom attributes to an AbstractFormType. Actually I do this job extending class FormTypes.

1. Adding my class TextAreaFormActivitiType extending AbstractFormType with attribute of textarea rows.
<code>
import org.activiti.engine.form.AbstractFormType;

public class TextAreaFormActivitiType extends AbstractFormType {

public static final String TYPE_NAME = "textarea";

private Integer _rows = new Integer(0);

public TextAreaFormActivitiType() {
}

public Integer getRows() {
return this._rows;
}

public void setRows(Integer rows) {
this._rows = rows;
}

@Override
public String getName() {
return TYPE_NAME;
}

@Override
public Object convertFormValueToModelValue(String propertyValue) {
return propertyValue;

}

@Override
public String convertModelValueToFormValue(Object modelValue) {
return (String) modelValue;
}

}
</code>

2. Extending class FormTypes (FormTypesExtended). I am using formValues elements to configure number of rows to print.

<code>
       <activiti:formProperty id="tipoAreaTexto" name="Tipo area texto" type="textarea" variable="tipoAreaTexto" required="true">
          <activiti:value id="rows" name="10"></activiti:value>
        </activiti:formProperty>

</code>

.. instead i would like to us this… :
<code>
       <activiti:formProperty id="tipoAreaTexto" name="Tipo area texto" type="textarea" variable="tipoAreaTexto" required="true" rows="10"/>
</code>

<code>

public class FormTypesExtended extends FormTypes {

public FormTypesExtended() {
super.addFormType(new StringFormType());
super.addFormType(new LongFormType());
super.addFormType(new DateFormType("dd/MM/yyyy"));
super.addFormType(new BooleanFormType());
}

@Override
public AbstractFormType parseFormPropertyType(FormProperty formProperty) {

if ("textarea".equals(formProperty.getType())) {

   Map values = new LinkedHashMap();
   Integer rows = new Integer(3);

   // Access formProperty values..
   for (FormValue formValue : formProperty.getFormValues()) {

    // Contains rows
    if ("rows".equals(formValue.getId())) {
     rows = Integer.parseInt(formValue.getName());
    }
   }

   // Create new type with rows..
   TextAreaFormActivitiType textAreaType = new TextAreaFormActivitiType();
   textAreaType.setRows(rows);

   return textAreaType;
}

return super.parseFormPropertyType(formProperty);
}
}
</code>

3. Adding configuration to spring-activiti.xml file.

<code>
   <!– adding this configuration to spring-activiti.xml –>
<bean id="formTypesExtended" class="com.inditex.tempe.activiti.types.FormTypesExtended">

<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
    <property name="formTypes" ref="formTypesExtended" />
     …

</code>

The XML doesn't allow adding additional attributes, pluggability should be done the way you described above. The activity:* elements are restricted by the XSD
