[T5.4] Dynamic Forms
Hi all,
I'm currently working on a report generation tool (using JasperReports in the background). The reports will consist of multiple components. Beside having "static" parameters, I will need runtime parameters shared across the different components. The challenge I'm facing now, is to create a dynamic form for this runtime parameters. I imagine to have a Map<String, Class> or a similar construct calculated from the from the different components. For example, the Map could look this:
"title" => java.lang.String
"date" => java.util.Date
"companies" => java.util.List<Company>
...
Is it possible to generate a dynamic form containing each of the parameters by loading a form fragment based on the given type?
Can I use the Dynamic component for it and if yes how (unfortunately, I couldn't find an example)?

All inputs are appreciated!
Thanks a lot and best,
Thilo

BeanEditor does that, so I don't think there's any need for you to
reimplement that. :)

Hi Thiago,
Thanks a lot for your prompt feedback! I will try to use the BeanEditor by contributing new property editors. I also thought about looping through the map entries and use the delegate component for the different field types. Let's see.
Best,
Thilo

BeanEditor/BeanEditModel already do that. See section Adding New Property
Editors in http://tapestry.apache.org/beaneditform-guide.html. Any further
questions, just ask. :)

I think BeanEditor/BeanEditForm with BeanModel and one or more
custom-written PropertyConduits is the way to go. BeanEditor already
creates form fields dinamycally. In this case, the values you need to edit
don't come from Java properties, so create a BeanModel using
BeanModelSource and use BeanModel.add(String propertyName, PropertyConduit
conduit) to add your Map-backed properties. PropertyModel is in interface
used by BeanModel to get and set value.
