<p class="MsoNormal" style="margin-bottom:12.0pt">As Edward says, there is no easy way to do this.<br>
One idea would be to set the visibility to expert:<br>
<br>
method.setVisibility(Settable.EXPERT);<br>
<br>
You would do this in attributeChanged().<br>
This would make method not visible the next time the <br>
EditParameters dialog was rendered. This is not really what<br>
you want.<br>

A couple of notes: <br>
<br>
The parameter names should match the field names. <br>
Otherwise, you will have problems if you use the actor <br>
in actor-oriented classes. If you want the user to see <br>
a different name, I suggest: <br>
<br>
enableOperation = new Parameter(this, "enableOperation"); <br>
enableOperation.setDisplayName("enableCatalogUpdate"); <br>

<p class="MsoNormal" style="margin-bottom:12.0pt">Dear All, <br>
<br>
I am a beginner trying to develop an actor. I apologize for asking a <br>
silly question. <br>
<br>
I need two parameter : the first is a Boolean and the second one a String : <br>
<br>
public Parameter enableOperation; <br>
<br>
public StringParameter method; <br>
<br>
enableOperation = new Parameter(this, "enableCatalogUpdate"); <br>
<br>
enableOperation.setTypeEquals(BaseType.BOOLEAN); <br>
<br>
enableOperation.setExpression("false"); <br>
<br>
method = new StringParameter(this, "populationRequest"); <br>
<br>
method.setTypeEquals(BaseType.STRING); <br>
<br>
method.setExpression("create"); <br>
<br>
method.addChoice("create"); <br>
<br>
method.addChoice("update"); <br>
<br>
I should like that the second parameter be available only when the user <br>
checks the first one. Is it possible to do that easily? <br>
<br>
Many thanks for any help. <br>

Jacqueline <br>
