Hello, So you cannot call groovy, or any other programming language for that matter, from your browser. The only thing you can call from the browser is javascript and the DOM.
So if you want to wire a button to some piece of code that you would like to execute, then this is simply a good-old http-request / http-response thing just like in any other technology / programming language / framework. So what you want to do, is to call an end-point that is defined in Controller.xml and pass whatever parameters you need to it, and from there now you're in server-land and you can do whatever you're used to in OFBiz. Note that it's quite different to call an HTTP end-point by submitting a form (the browser does it) vs calling it from Javascript (you do it) because in the latter case you are not redirected to another page. In other words, perhaps the problem is simply not differentiating between what is server-side code and client-side code. If you make the distinction clear then you just realize it's a matter of HTTP communication between the two. I hope this helps!

E.g Add a button on the product measures form to calculate the volume given a product's dimensions.. I've tried <field name="calcTest" title=" " widget-style="buttontext"> <hyperlink description="Calculate C" target="testCalc" also-hidden="false"> <parameter param-name="scale-factror"/> <!-- e.g add an allowance for packing material --> </hyperlink> </field> I can call/test the service "testCalc" from webtools etc but not use the button. Can anyone point me to an example in the existing code base that I can use as a reference model. thanks in advance Ernest
