Accordion setSelectedIndex issue
Hi
I faced with issue while refreshing my accordion view.
Let say I have one accordion and one button refreshing accordions data and
setting index.
nextCompanyButton.getButtonPressListeners().add(new
ButtonPressListener() {
@Override
public void buttonPressed(Button button) {
companiesAccordion.getPanels().remove(0,
companiesAccordion.getPanels().getLength());
CompanyViewController companyView =
UIComponents.companyView();
companyView.load(new BeanAdapter(new Company()));
Accordion.setLabel(companyView, "T1");
companiesAccordion.getPanels().add(companyView);
companyView = UIComponents.companyView();
companyView.load(new BeanAdapter(new Company()));
Accordion.setLabel(companyView, "T2");
companiesAccordion.getPanels().add(companyView);
companiesAccordion.setSelectedIndex(1);
}
});
As you can see, i'm removing all the panels and initing them from the
scrach.
So when i'm setting selection index to 0 it is ok no artifacts appears, but
if it is 1 accrodion is flipping. I mean the accordion area is getting blank
for a second or half and then is back to normal with right panel selected.
Seems like that half a second perion selection transition is done. But there
is no animation on screen.
So finally, I need to refresh my accordion and set correct panel index. Can
you tell me how can i do that without that flipping affect?
Perhaps I can turn off that selection animation while refresh or something?
Thanks, Eugene

You discovered an interesting issue. I just checked in a fix - however, it looks like you are using Pivot 1.5 and the fix was made for 2.0. If you want to manually patch the source for 1.5.2, here is the diff:

Any chance you could provide a simple app that demonstrates the issue?

I am not in a position to be able to see how this manifests, but it sounds
like it could be this issue https://issues.apache.org/jira/browse/PIVOT-572
If so, you might be able to hack together a workaround using a CardPane and
maintaining 2 Accordions. The card pane would show the one that is in a
good visual state while you populate the empty one, then toggle the
CardPane's selection to the newly populated one, and clear the first
accordion ready for the next set of changes. A very clunky double-buffering
effect...
Or if you want to take a look into the issue itself, you'll probably need
http://svn.apache.org/repos/asf/pivot/trunk/wtk-terra/src/org/apache/pivot/wtk/skin/terra/TerraAccordionSkin.java
