Hello Matthias,
Thank you for your help.
The problem was indeed that I did not add poll-comp to the partial target.
Now I changed the listener as (it happens after navigation):
private class AccountPeriodRefreshCollectionListener implements
RefreshCollectionListener {
public DataPage refreshCollection(List<SortCriterion> sortCriteria,
int rangeStart, int rangeEnd) {
setInterval(1000);
RequestContext.getCurrentInstance().addPartialTarget(pollingComponent);
}
}
Another problem was that table was after the poll component in the jsp. So,
it did not work. I placed the poll component after the table:
<tr:table id="tr1" width="550" var="period"
partialTriggers="::pollBalances"
value="#{accountBean.accountPeriodsCollectionModel}" rows="25"
horizontalGridVisible="false" verticalGridVisible="true">
...
</tr:table>
<tr:poll pollListener="#{accountBean.onPoll}"
interval="#{accountBean.interval}" id="pollBalances" />
So, now first listener for the table is called, which also changed the
interval for the poll component. Then poll component is rendered and the new
value for the interval is picked up.
Great, it works after few days of struggling :)
Thanks a lot, Lena
