Getting the Selection from NEW wizard in Eclipse [message #641140]

Hi Guys,

I have added a new Wizard entry in my plugin.xml which goes like this

 <wizard
            name="Workflow"
            icon="icons/bpd.gif"
            category="com.***.bpdesigner"
            class="com.***.bpdesigner.BPCreationWizard"
            id="com.***.bpdesigner.WorkflowCreationWizard">
         <description>
            Creates a workflow
         </description>
         <selection
               class="org.eclipse.core.resources.IResource">
         </selection>
      </wizard>

What I want to do is to somehow check in BPCreationWizard.java (the configured class, which is instantiated by the new wizard) which FILE TYPE was chosen from the new Wizard dialog.

We are using "BPCreationWizard" as the class name for two different file types viz. Microflow and Workflow.

The only way forward as of now is to extend another class from BPCreationWizard which will set a flag saying that it is a workflow and mention this class in Workflow configuration in plugin.xml .. but having a new class which delegates most of the work to the base class does not sound good.

Is there any way by which I can figure out in MY WIzard class as to which OBJECT was selected in the NEW wizard??

When I click next my configured class is instantiated. So in the constructor of "BPCreationWizard" I want to somehow see which item was selected from the NEW wizard.

I am a newbie on plugin development; any help would be appreciated.

Thanks,
Ragz

Okay now this works out for me Smile

But I am sure there must be a better way if at all .. any help appreciated thanks.

	try{
		Object data = PlatformUI.getWorkbench().getDisplay().getActiveShell().getData();
		if(data instanceof WizardDialog){
			WizardDialog dialog = (WizardDialog)PlatformUI.getWorkbench().getDisplay().getActiveShell().getData();
			String description = dialog.getCurrentPage().getDescription();
			
			if(description != null && description.toUpperCase().contains("WORKFLOW")){
				this.workflow = true;
			}
		}
		}catch(NullPointerException e){
			//DO nothing
		}

You wizard could implement IExecutableExtension and then pass on the
type from the plugin.xml.
