How to provide informations to a FormPropertyRenderer

Hi,My form has an output string given by the setting of a group of radio buttons.I need to decide at runtime if this group of radio buttons should display or not.So I think I should provide an input variable to the form renderer so that it can call services to know if the buttons should display or n

Are you implementing a form renderer in Vaadin? Or are you writing your own custom renderer?
In the latter case I would advise to get a process variable using the RuntimeService and interpret its value.

Best regards,

Hi,

Thanks for your answer!

Yes, this a Vaadin form renderer. It extends org.activiti.explorer.ui.form.AbstractFormPropertyRenderer

I looked at RuntimeService and all getVariable*(…) method require at least a process id, which does not seam to be available within the context of a FormPropertyRenderer configuration:

<code>
public Field getPropertyField(FormProperty formProperty) {…}
</code>

Am I wrong?

Best regards,
Martin

Afaics, there is indeed no way to get the current execution or process instance.
Imho, this is missing feature which must be added to make it usable.
