Hi,
In my plugin code, I'd like to determine the current (active) chart. For context variable of type IPluginContext I call getLastActiveChart().
As a result I get the active tab chart object - this is OK.
But when this code is run just after starting the platform (without clicking on any tab) - accessing the chart object is not possible - it ends with IllegalStateException (until I click on any tab).
Best regards, Marcin

The workaround for this case is to set programmaticaly one of the existing tabs as active.
private IChart getActiveChart() {
IChart ret = context.getLastActiveChart(); if (!ret.isAlive()) { // we've got non-accessible chart object Set<IChart> currentCharts=context.getCharts(); if ((currentCharts==null)||(currentCharts.isEmpty())) return null; IChart chart = currentCharts.iterator().next(); chart.setFocus(); // switch to this tab return chart; } return ret; }
