Many thanks for your answer. In fact, I thought to a workaround : I can have only one string Parameter with three choices instead of two : "none", "create", "update". But it is not so "pretty" as what I want!
Many thanks to Edward for your comment about the parameter names / fields names : I did not know this constraint.

One idea would be to set the visibility to expert: method.setVisibility(Settable.EXPERT); You would do this in attributeChanged(). This would make method not visible the next time the EditParameters dialog was rendered. This is not really what you want. _Christopher On 11/30/12 10:13 AM, Edward A.

Otherwise, you will have problems if you use the actor in actor-oriented classes. If you want the user to see a different name, I suggest: enableOperation = new Parameter(this, "enableOperation"); enableOperation.setDisplayName("enableCatalogUpdate"); Edward On 11/30/12 1:42 AM, SIGNORET Jacqueline 139795 wrote: Dear All, I am a beginner trying to develop an actor. I apologize for asking a silly question. I need two parameter : the first is a Boolean and the second one a String : public Parameter enableOperation; public StringParameter method; enableOperation = new Parameter(this, "enableCatalogUpdate"); enableOperation.setTypeEquals(BaseType.BOOLEAN); enableOperation.setExpression("false"); method = new StringParameter(this, "populationRequest"); method.setTypeEquals(BaseType.STRING); method.setExpression("create"); method.addChoice("create"); method.addChoice("update"); I should like that the second parameter be available only when the user checks the first one. Is it possible to do that easily? Many thanks for any help.
