Setting form property required/writable/readable attribute values with an expression

[jim1]

Is it possible to do the following, or something similar?

<activiti:formProperty id="someProperty" name="Some Property" type="boolean" required="${isRequired}" readable="${isReadable}" writable="${isWritable}"></activiti:formProperty>
‍‍‍

(assuming the variables in the expressions have been set up correctly)

My investigation so far suggest it isn't possible to do this, but I just wanted to check I wasn't missing a trick somewhere before writing the idea off.

Thanks.

Hi Jim,

I think you are right


  protected boolean readable = true;
  protected boolean writeable = true;
  protected boolean required;

The values are resolved during parsing. (are not evaluated during runtime.
You can change implementation easily.

Thanks Martin, will take a look.

Jim,

Did you do anything in this area?

I have a situation where completing a task can cause the process instance to take one of several paths and certain form properties are required for one of the paths.  So I'd like to be able to conditionally say they are required depending on the action specified.  Is there a way to do this?

The typical bpmn way would be to use an exclusive gateway with conditions on the outgoing sequence flow.
