Hello, I'm not sure you could trigger the button directly from a plugin but you could re-use the component and its underlying actions code. The ui code is here http://code.google.com/p/taverna/source/browse/taverna/ui/net.sf.taverna.t2.ui-components/trunk/results-view/src/main/java/net/sf/taverna/t2/workbench/views/results/workflow/WorkflowResultsComponent.java
look at the SaveAllAction inner class, it handles finding out what save actions are available and the action to take when clicked. The 'save' types are found by SPI and are detailed here - http://code.google.com/p/taverna/source/browse/taverna/ui/net.sf.taverna.t2.ui-components/trunk/results-view/src/main/java/net/sf/taverna/t2/workbench/views/results/saveactions/ they all extend http://code.google.com/p/taverna/source/browse/taverna/ui/net.sf.taverna.t2.ui-components/trunk/results-view/src/main/java/net/sf/taverna/t2/workbench/views/results/saveactions/SaveAllResultsSPI.java I guess the key thing is to make sure that the action can find the results - not 100% sure how it does that because I haven't got the code checked out on my machine at the moment.
