Hello,
at work I may convert a Struts application into a Woody one. I played around with the Woody samples and created a form handling prototype for my application. But I came across some problems and made some observations I want to point out here. On the other hand the architecture is not "fixed", especially the communication with the backend, so the handling of the business logic is not that perfect.
1. When the template contains a reference to a not defined widget, I get an exception: "EffectWoodyTemplateTransformer: Widget with id "addcontact" does not exist in the container."
What would be helpful in this error message is the mentioning of the file and the line number.
2. When a flow script function is not available (called via woody2.js, line 213) I only get a "CascadingRuntimeException: The undefined value has no properties." Isn't it possible to give a more exact explanation or at least to point to the expression that returns undefined?
You could change the code to this:
function woody(form_function, form_definition) {
var form = new Form(cocoon.parameters["form-definition"]);
var args = [form];
// set the binding on the form if there's any
var bindingURI = cocoon.parameters["bindingURI"];
if (bindingURI != null)
form.createBinding(bindingURI);
var funName = cocoon.parameters["function"];
var fun = this[funName];
if (!fun) {
throw "Function \""+funName +"\" is not defined";
} else if (!(fun instanceof Function)) {
throw "\""+funName +"\" is not a function";
}
fun.apply(this, args);
}
