</div></div>I think this is a bug introduced during the sdm refactorings, and I<br>
also reproduced it once<br>
but did not have time to investigate it yet.<br>
<br>
If the code expect the replace a volume path during runtime, we should<br>
have a setter:<br>
<br>
@property<br>
def volumePath(self):<br>
return self._volumePath<br>
<br>
@volumePath.setter<br>
def volumePath(self, value):<br>
self._volumePath = value<br>
<br>
You can try add this to the manifest class and see if it fixes this issue.<br></blockquote><div><br></div><div><br></div><div>Which class is it? Where is it located?</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
