Hello everybody.<br>
I'm having problems trying to apply a particular stereotype (the
"Overrides" stereotype from the Theme/UML profile:
<a class="moz-txt-link-freetext" href=" https://www.cs.tcd.ie/Eamonn.Linehan/lero/ThemeUML.profile.u ml"> https://www.cs.tcd.ie/Eamonn.Linehan/lero/ThemeUML.profile.u ml</a>).<br>
The rest of the stereotypes I used applied correctly with no problems,
but each time I try to use "Overrides" I get the following error
(independently of the type of element I'm applying it to):<br>
<font color="#ffff00"><br>
<font color="#3333ff">java.lang.NullPointerException<br>

<br>
Which could be the reason?, perhaps the profile was made with a
different version of UML2/EMF/Eclipse?.<br>
Any suggestions would be greatly appreciated.<br>
