Hi, I'd like to do something slightly unusual and wrap the wicketSubmitFormById call in another javascript function -- I'm able to do this with no problem by overriding AjaxFormSubmitBehavor.onRenderHeadInitContribution and calling JavascriptUtils.writeJavascript on a wrapped getEventHandler. I can stop the normal attribute for 'onclick' or whatever from appearing inside the component tag by overriding onComponentTag. And by using text input boxes, I can pass 'arguments' to my method on the server inside using FormComponent.getConvertedInput. So far so good.
The problem I have is that I'd like to actually 'return' a value back from the server in that Javascript function... so my function ends up looking just like a normal function call inside of my Javascript and returns the value that the server provides. I can see inside of wicket-ajax.js that there are three special tags: "component", "evaluate" and "header-contribution", each with their appropriate purpose -- I tried messing around with AjaxRequestTarget.prependJavascript so I could pass something through the 'evaluate' tag, but my javascript isn't sufficient to the task. Then I tried using AjaxRequestTarget.addComponent to modify another TextField and return the value through the DOM tree -- that works fine except for the fact that the order is wrong, so my method returns _before_ the component is updated. Then I noticed this interesting Wicket.Ajax.invokePostCallHandlers() call, which makes me wonder if there is already some nice clean mechanism in place for updating javascript variables thru wicket's java code. Apologies if this all makes no sense, but any advice or suggestions would be much appreciated. The basic requirement is just that I make a call in Javascript and get data back from the server as a 'returned' variable on the client.
