[CFORMS] dynamic binding
Does anybody know a clean approach for dynamic binding. For example it
would be nice to use a JXTemplate for the binding and pass it some vars
like it works with showForm:
form.createBinding("binding.jx", {"param1": somevalue, "param2":
somevalue});
I know it's possible to solve this with a special pipline and call the
binding with /binding.jx/param1/param2
But that's ugly IMO.

Thanks for your answer. I think that Bruno's suggestion (passing
parameter in form.load instead() of form.createBinding() ) is perfect
for me.

You should be able to pass an arbitrary number of attributes. I was
thinking something like:
cocoon.request.setAttribute("param1", "value1");
cocoon.request.setAttribute("param2", "value2");
//...ad nauseum
form.createBinding("cocoon://binding.jx");
...then in your jx template:
<jx:set var="param1" value="${cocoon.request.getAttribute('param1')}" />
<jx:set var="param2" value="${cocoon.request.getAttribute('param2')}" />
etc...
This is untested but seems to me like it should work.
If you didn't want to pollute the request object with so many attributes
you might be able to use a single request attribute with a JS object as
its value: c.r.setAttribute("data", {param1:"value1", param2:"value2"});
you'd have to figure out how to traverse the JS object within the
template... I think JXPath expressions could do so.

Thank you Bruno! That was exactly what I was looking for. I don't know
why I never tried to pass the parameter in form.load() instead of
form.createbinding(). This is perfectly clean and easy. Thank you!

I'm not sure what kind of dynamism you need, but if it is in the JXPath
expressions you can pass parameters to the binding along with your
'bussiness object':
form.load({"data": dataObject, "param1" : "value1", "param2" :
"value2"});
In the binding you'll then need to adjust the fb:context to start form
"/data". The parameters are accessible in JXPath expressions using e.g.
"/param1".

That's how I'm doing it right now. But in some cases that is not enough.
Especially when you want to pass more than 3 parameters to the binding.

Looks like somebody posted a patch for this feature:
https://issues.apache.org/jira/browse/COCOON-1418
In the meantime you can use request attributes or parameters as a
transport for your data.
