p:graphicImage updated 3 times

[racadent]

Hello,

I have a datatable component and when I select the row in the table I update chart with the new data. But the problem is that chart's method (getHours()) which returs data for the chart is called 3 times consecutively (so I have unnecessary 3 queries instead of one).

chart:

Code: Select all

<p:graphicImage id="chart" value="#{chartBean.hours}" cache="false" />

bean's method:

Code: Select all

public StreamedContent getHours() {
		StreamedContent chart = null;
		if (selectedService != null) {
			hours = report.getServiceGroupingReport(dateFrom, dateTo, selectedService.getServiceID(), "hh24");
			chart = createChart(hours, "hours");
			oldSelectedService = selectedService;
		}
		return chart;
	}

Thanks

The getter methods shouldn't contain any logic.
