---------------------------------------
Summary: Allow AJAX callback function generation to also generate
parameters
Key: WICKET-4540
URL: https://issues.apache.org/jira/browse/WICKET-4540
Project: Wicket
Issue Type: Improvement
Components: wicket
Affects Versions: 6.0.0-beta1
Reporter: Emond Papegaaij
Assignee: Emond Papegaaij
We need an easy way to pass parameters from JavaScript to Java via a function
that takes parameters. For example, of JQuery UI event callbacks, the function
takes two parameters: event and ui. But, these aren't the parameters you want
to pass to Java. A conversion is needed.
I was thinking about the following: let getCallbackFunction take a
CallbackParameter vararg, with 4 implementations for CallbackParameter:
ContextParameter, ExplicitParameter, ResolvedParameter and ConvertedParameter.
A context parmater, only provides context to the function, it is not added to
the Ajax call. Both event and ui are context parameter. Explicit parameters are
context parameters that are also passed to the Ajax call. Resolved parameters
are resolved using some javascript code. The last adds a context parameter and
a conversion script to add it to the Ajax call.
