Re: [bpel-dev] How to change the default behavior of LeafBorder.paint()

[zeng zhen <zengzn@xxxxxxxxx>]

Hello, Michael,

thank you for your answer.
I still have a question about creating an extension point in bpel.ui.

I have defined an extension point with name "customvisual" in plugin.xml of bpel.ui

I have added following codes in org.eclipse.bpel.ui.editpart.border.LeafBorder to create an instance of the extension. 
ÂÂÂ protected void getExtensionLeafBorder() {
ÂÂÂ ÂÂÂ 
ÂÂÂ ÂÂÂ instance = null;
ÂÂÂ ÂÂÂ 
ÂÂÂ ÂÂÂ instance =Â (LeafBorder) BPELUIRegistry.readCustomvisual("extension.leafborder");
ÂÂÂ ÂÂÂ if (instance == null) {
ÂÂÂ ÂÂÂ ÂÂÂ return ;
ÂÂÂ ÂÂÂ }
ÂÂÂ }

This instance is used in paint(IFigure figure, Graphics graphics, Insets insets) to adjust the visualization of the activity nodes.
My question is: is there a way to avoid modifying the source code of org.eclipse.bpel.ui.editpart.border.LeafBorder? Because the hardcoding is always bad.

thanks!

Hello Ting,

as of today we don't have the possibility to adjust the visualization of the activity nodes using extension points.
So the answer is, yes - you would have to define an extension point in bpel.ui.
