Hi Geoff,
Thanks, it helped a lot.
I actually had some problems because I have several texts to show, so
the onActivate() was deciding the id of the text shown on the current
screen.
The onTrack() later needs to annotate the tracking values together with
the text id.
But then I moved all the code of the onActivate() to the setupRender()
and passed the text id as a parameter of the ZoneUpdater
(ZoneUpdater.userStageId="${userStage.userStageId}"):
<p class="paragraph" t:type="any" t:mixins="zoneUpdater"
ZoneUpdater.clientEvent="mousemove" ZoneUpdater.event="track"
ZoneUpdater.zone="textZone"
ZoneUpdater.userStageId="${userStage.userStageId}"
ZoneUpdater.fields="['documentHeightVal',
'documentWidthVal', 'windowHeightVal', 'windowWidthVal',
'windowOffsetYVal', 'windowOffsetXVal', 'mouseYVal',
'mouseXVal', 'domPathVal', 'overTextVal']">${currentParagraph}</p>
That worked. I tried to do the same thing passing the text id to another
input hidden like the rest, but it didn't work.
Now I have to do some extra work in the onTrack(), but it is not as much
as the one being done in the setupRender().
