title: Eclipse Plug-in:How can we show/hide a particular wizard entry based on certain conditions?
body: <p>I have a custom wizard entry in File->New->Other->Web->MyEntry. </p>
  
  <p>I want this entry to show up only on </p>
  
  <p>1)selection of particular project type(as in when I do a right click on that Project->New->Other->Web->MyEntry or when that particular project is selected.</p>
  
  <p>2)Some particular folder in that projec type is selected</p>
  
  <p>I am able to get my project type and also able to validate the folder which is associated with the project type. Earlier, I used property tester to get my work done for a similar situation for a context menu. Do we need to use a property tester or is there any other specific way which has to be used inside a <code>&lt;wizard&gt;</code> tag.</p>
