[ome-users] QueryService

[Woodbridge, Mark R]

Many thanks Josh. This seems to do the trick:

if (!tsp.setPixelsId(pixelsID)) {
	tsp.resetDefaults();
	tsp.setPixelsId(pixelsID);
}

Mark.

No worries; that certainly makes a lot more sense.

Right. If the return value from setPixelsId is false:

http://hudson.openmicroscopy.org.uk/job/OMERO/javadoc/ome/api/ThumbnailStore.html#setPixelsId%28long%29

you will definitely need to take further action before things will
work, specifically call resetDefaults and then re-call the set methods:

http://hudson.openmicroscopy.org.uk/job/OMERO/javadoc/ome/api/ThumbnailStore.html#resetDefaults()

I went ahead and added a ticket to make the exception clearer:

http://trac.openmicroscopy.org.uk/omero/ticket/1616

Thanks for pointing this out.
