title: Tibco Spotfire webplayer, set a document property via the url
body: <p>I am trying to do something simple in Tibco Spotfire, to try and set a document property in webplayer by specifying a property in the url.  I cannot get this to work.</p>
  
  <p>I have created a document property called 'test' which is simply a string</p>
  
  <p><a href="https://i.stack.imgur.com/Bq9Oa.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Bq9Oa.png" alt="Image of document property"></a></p>
  
  <p>I have then created an input text control bound to that document property</p>

  <p>I would expect that if I opened that report in webplayer with a url prepended with &amp;configurationBlock=test%3D"helloworld" then the input text would be populated with the value helloworld.  However, it is not.</p>

  <p>This seems to be a reasonably simple thing to get working, I have tried what I think is every possible variant of encoding the data to no effect.  Is there something I am doing wrong that could make this work.</p>
