you inspect this?</p>
<p>Also - does it still happen if you don't mediate the popup?</p>

<p>As im using profiler im clicking on the run GC button after i
already have more than three cumulative instances of the skin and
component in the heap.</p>
<p>The second part i need to run tests on.</p>
<p>One more thing is , im not pointing a finger at RL it very well
might be something that i dont yet know or a glitch in the SDK
etc</p>
<p>Thanks in advance</p>

function - so not there.<br>
And closed in a mediator - but is the mediator is cleared out of
the heap the things he points to should be removed as well.</p>
<p>There is the stylemanager that pairs a view with his skin but i
doubt he is envolved with this issue.</p>
<p>Really out of ideas here...</p>
<p>Is there a way to check out references of an object that is
allocated in the memory in a given time? This kind of a trick could
really give us some clues.</p>
<p>Thank you</p>

creating<br>
the popup in? If so, that would create a closure holding on to
the<br>
popup. In that case, either create the function outside and
just<br>
reference it in the outer function or explicitly null the var<br>
referencing the popup.</p>
<p>And yes: You can see references to all live objects in the
Flash<br>
Builder or the FDT profiler. See the respective documentation
for<br>
details.</p></div>Till Schneidereittag:robotlegs.tenderapp.com,2009-10-18:Comment/82915422011-07-04T13:18:27Z2011-07-04T13:18:27ZPopups partly not removed from memory.<div><p>Will check the references thing via profiling.THANKS :)</p>
<p>About the local function : Im creating and adding the popup at
"execute" of a command as a local var cause i need it to initiate a
mediator based on that view. But the var is local to a function
that gets cleared after the command does his thing. So no
references should be present there. Wrong?</p>

method.<br>
An example for that would be an event handler.</p>
<p>Other reasons for the popup staying in memory could be event
handlers<br>
added to something outside of the popup from inside it.</p>
<p>But really, it doesn't sound like the problem is
Robotlegs-related, so<br>
using the profiler is probably your best chance.</p></div>Till Schneidereittag:robotlegs.tenderapp.com,2009-10-18:Comment/82915422011-07-04T13:34:33Z2011-07-04T13:34:33ZPopups partly not removed from memory.<div><p>Didn't checked it yet but... might it be that the model is
holding a "pointer" to a same object that the component got as a
data????</p>
<p>:) never accused RL just saw some sharp minds around. And asked
for help. RL rocks!</p></div>trostiktag:robotlegs.tenderapp.com,2009-10-18:Comment/82915422011-07-04T13:45:34Z2011-07-04T13:45:34ZPopups partly not removed from memory.<div><p>No, having an external reference to an object that you also hold
a<br>
reference to from inside the popup isn't going to be a problem.</p>
<p>While generally, asking questions that are only loosely related
to<br>
Robotlegs is of course fine, but please understand that we'd very
much<br>
like for people to make it clear when they don't suspect that
the<br>
problem really is related to Robotlegs. For one, it prevents us
from<br>
looking in wrong direction when trying to help you.</p></div>Till Schneidereit
