    Hi,<br>
    <br>
    I was working with Fuel to save and load a Roassal view (serialize
    and materialize), and everything works perfect (so far) except for
    one thing: if I have an Anouncer which its registry has an
    announcementSubscription with a nil subscriber, it does not work is
    gives me this error: <br>
    <br>
    <img src="cid:part1.01050106.05030501@gmail.com" alt=""><br>
    <br>
    Standard Roassal interactions are OK, but if I do:<br>
    <br>
    aRoElement on: ROMouseClick do: [something] in a Wokspace
    materialization does not work. If I execute the same code in a
    method send as message to an object I have not this error and
    materialization works perfectly. This means I can not save some
    visualizations created in the Workspace.<br>
    <br>
    Have anyone experience something like this?<br>
    <br>
    Thanks,<br>
    Vanessa.<br>
