How do I dynamically set the readOnly attribute for a field property?

I am trying to figure out how to dynamically set the readOnly attribute for several fields in a large form. My process and form are rather complicated, so I'm going to simplify it for this post:My Users:FormCompleterFormReviewerMy Processtep 1: FormCompleter fills out the fields in the form.Step 2

Did you tried over-riding of in-build types and rendering services?
I think that should resolve your problem.

For e.g. for text field you may be using "string" as form type. you can build your own type like "custom_string" and your own form rendering service which will handle the logic for edit/ready only mode. Rendering Java class can be a spring bean that have access to user information.

<java>
import org.activiti.engine.form.AbstractFormType;

public class TextAreaFormType extends AbstractFormType {

private static final long serialVersionUID = 1L;
private static final String TEXT_AREA_TYPE = "textarea";

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

public String getMimeType() {
return "text/plain";
}

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

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

}
</java>

<java>
import org.activiti.engine.form.FormProperty;
import org.activiti.explorer.ui.form.AbstractFormPropertyRenderer;

import com.jpmorgan.bpm.activiti.form.type.TextAreaFormType;
import com.vaadin.ui.Field;
import com.vaadin.ui.TextArea;

public class TextAreaFormPropertyRenderer extends AbstractFormPropertyRenderer {

private static final long serialVersionUID = 1L;

public TextAreaFormPropertyRenderer() {

super(TextAreaFormType.class);

}

public Field getPropertyField(FormProperty formProperty) {

TextArea textArea = new TextArea(getPropertyLabel(formProperty));
textArea.setRequired(formProperty.isRequired());
textArea.setEnabled(formProperty.isWritable());
textArea.setRequiredError(getMessage("form.field.required", new Object[] { getPropertyLabel(formProperty) }));
if (formProperty.getValue() != null) {
textArea.setValue(formProperty.getValue());
}

textArea.setHeight("100px");
textArea.setWidth("608px");

return textArea;

}

}
</java>

Thanks for the tip. I have not tried that, and I had to move on because I'm on a short schedule.

In the meantime, I'm just using different forms and using the Display Value fields in the second form. It's no fun keeping the forms in sync, but it was the best method given my time constraints.

I'll check out the override idea when I have a chance to refactor at a later time.
