Hello,
When trying to add tools to the chart at runtime i get

java.lang.NullPointerException
	at javax.swing.ImageIcon.<init>(ImageIcon.java:181)
	at com.steema.teechart.editors.Renderer.getListCellRendererComponent(ToolsGallery.java:341)
	at javax.swing.plaf.basic.BasicListUI.updateLayoutState(BasicListUI.java:1344)
	at javax.swing.plaf.basic.BasicListUI.maybeUpdateLayoutState(BasicListUI.java:1294)
	at javax.swing.plaf.basic.BasicListUI.getPreferredSize(BasicListUI.java:561)
	at javax.swing.JComponent.getPreferredSize(JComponent.java:1634)
	at javax.swing.ScrollPaneLayout.layoutContainer(ScrollPaneLayout.java:769)
	at java.awt.Container.layout(Container.java:1421)

This is in my application, but it must also happen in the teechart examples\application1 beacuase the window is not opened there as well.

Please help,
Avi

Hello Avi,

The majority of tools in the demo are added at runtime and I've opened the Swing precompiled demo shipped with TeeChart Java Suite with sources v3.2014.0519 (\Examples\Swing\Features\TeeChart.Features.jar) and I moved along all the tools section without finding errors.

Am I missing anything?

hi Yeray,
In \Examples\Swing\Features\TeeChart.Features.jar
Go to whatever example you want - In the Commander --> Edit --> Tools --> Add - is not opening.

Hello,

I see SeriesRegion.gif was missing in that build and it causes the Tools Gallery to fail.
Put this file into the "\src\Swing\com\steema\teechart\tools\icons" folder to fix it.
