[Wicket-user] Is it possible to use setMarkupStream to assign html to a web page?
I've got some groovy code which processes an xml file and generates some html. Right now I do it at build time, but would really prefer to do it at run time. I've got some code hooked up which does so, but all I get is an empty page. I'm using wicket 1.3.0-snapshot (prior to the name change) when building the page, I run the following groovy code, where the buffer contains the html I generate. MarkupParser parser = new MarkupParser( new XmlPullParser() ) Markupmarkup = parser.parse( buffer ) def markupStream= new MarkupStream( markup ) page.setMarkupStream( markupStream ) I've tried overriding onRender in the page java code and calling renderComponent with my markup stream, but I still don't get anything showing. It works with the same html generated at build time. Am I way off base and this just won't work, or do I have some details mucked up?

see IMarkupResourceStreamProvider, there is also an example in wicket-examples that shows custom markup loading. -igor On 5/3/07, Thomas R.

I think I'll have to go with the build time option because the getMarkupResourceStream( container, containerClass ) method gets called before any code in my constructor has a chance to look at the PageParameters to find out where the xml file is to be able to build the html. I don't see any way to delay the markup processing/loading until after I can examine the PageParameters. -igor On 5/3/07, Thomas R.

Re: [Wicket-user] Is it possible to use setMarkupStream to assign html to a web page?
Sounds like a similar bug I had with overriding getVariation on WebPage. This is now fixed in 1.2.6. The wicket authors had to rearrange the ordering of initialization to ensure that my constructor got called before the call to my overridden getVariation method. It could be that they may have to do a similar thing for your case. At the time I proposed a two phase initialization solution like most OO frameworks have adopted: Phase 1: Constructors are called and allowed to return resulting in fully constructed objects. Phase 2: The framework calls 'init' on the fully constructed object - at this point init will be working on fully constructed objects and so avoid the issue I had and the issue you are having with parameters not yet being processed and member data and relationships possibly not being in the correct state. The wicket authors prefer the current, single phase construction approach, over a two phase initialization approach because it avoids the task of writing 'init' methods but given that just about every other OO framework I've ever used uses two phase initialization of objects I think that wicket will continue to suffer bugs like yours and mine. As wicket's popularity snowballs they're going to get more and more propeller head users like you and me that have a great idea and then try and implement it in wicket - often going where no man or woman has gone before and pushing things to the edge of breaking. To date they've been able to rearrange things under the bonnet to work around my issue and I hope they can do that with your issue too but I fear that one day someone is going to come up with a great idea that won't elegantly work with a single phase construction/initialization mechanism. I don't know how what the outcome of that would be. hrm. i would consider that a bug i think. i dont see why it would get called before constructor. can you set a breakpoint in there and paste the stacktrace please. -igor On 5/3/07, Thomas R.
