Session Error - Cannot call getObject on :display.session on a user form

Question

On an end user form I have a manager label.
The manager attribute in the user object holds the unique identifier but I must display the full name.
<br><br>
So I have the following code to go get the fullname:
<br><br>
<block>
<invoke name='getAttribute'>
<invoke name='getObject'>
<ref>:display.session</ref>
<s>User</s>
<ref>accounts[Lighthouse].sponsor</ref>
</invoke>
<s>fullname</s>
</invoke>
</block>
<br><br>
Now it does go ahead and display the fullname but at the same time throws the following error on the page:
<br><br>
ERROR:XPRESS exception ==> com.waveset.util.WavesetException: Can't call method getObject on class com.waveset.session.LocalSession ==> com.waveset.util.InternalError: ID not passed to ObjectCache.getObject
<br><br>
Since it is not a workflow I think I need to use the :display.session reference.
<br><br>
Is there another approach I could try? Do you have any suggestions?

Answer 1

You could also use the following for your session:
<br><br>
<invoke name='getCache'>
                  <new class='com.waveset.session.InternalSession'/>
</invoke><br><br>
But the biggest problem I see is the string value User. I think it needs the following:
<br><br>
<invoke name='findType' class='com.waveset.object.Type'>
                    <st>User</st>
</invoke><br><br>
Note: I used st instead of s to avoid a strikethrough.
<br><br>
If I'm not mistaken, your code could then look like this:
<br><br>
<block>
<invoke name='getAttribute'>
  <invoke name='getObject'>
      <invoke name='getCache'>
                  <new class='com.waveset.session.InternalSession'/>
      </invoke>
      <invoke name='findType' class='com.waveset.object.Type'>
                    <st>User</st>
      </invoke>
       <ref>accounts[Lighthouse].sponsor</ref>
  </invoke>
  <st>fullname </st>
</invoke>
</block> <br><br>
