Re: Can i display a WepPage in a PDF (How to get the rendered markup)?
I created a quickstart but didn't create a ticket yet, because I found out that ComponentRenderer expects to get a component whose markupId equals to ComponentRenderer.COMP_ID. Is this a bug or a feature? Is there some way to render the markup of an existing component that has an arbitrary markupId using ComponentRenderer? I tried calling #setMarkupId and wrapping the existing component to a new component with expected markupId but both ways failed. Would it be easy to enhance ComponentRenderer to work with any markupIds? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Can-i-display-a-WepPage-in-a-PDF-How-to-get-the-rendered-markup-tp4659290p4659415.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Hi, This can be relaxed. Please file a ticket.

Hi,
Since Wicket 6.7.0 there is ComponentRenderer class which does exactly the
same.

Re: Can i display a WepPage in a PDF (How to get the rendered markup)?
FYI: I had a problem using ComponentRenderer with ListView (it was complaining the there was no markup for wicket-id my-wicket-id). Additionally, ITextRenderer (or xerces actually) was not able to parse XML from the markup with Wicket tags (The prefix wicket for element wicket:container is not bound.). I found another solution here: http://stackoverflow.com/a/11898702/536265 Then I added this before rendering: IMarkupSettings markupSettings = component.getApplication().getMarkupSettings(); boolean originalStripWicketTags = markupSettings.getStripWicketTags(); markupSettings.setStripWicketTags(true); And to the finally block: markupSettings.setStripWicketTags(originalStripWicketTags); If you think ComponentRenderer could/should be improved, maybe this will give you some ideas. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Can-i-display-a-WepPage-in-a-PDF-How-to-get-the-rendered-markup-tp4659290p4659352.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Can i display a WepPage in a PDF (How to get the rendered markup)?
Hi Edvard, Thank you for the feedback. ComponentRenderer (CR) just asks Wicket to render a component. The rendering process uses all the application settings so if the wicket tags/attributes cause any problems then the application can turn them off before using CR and turn on after. So I think CR doesn't need to be changed to have this code in itself. In production mode Wicket strips these tags and attributes unless you explicitly turn them on.

Can i display a WepPage in a PDF (How to get the rendered markup)?
Hi, i would like to render a WebPage with flying saucer (PDF generator). I've created a resource reference and a ByteArrayResource. But now i need the rendered markup of the page (e.g. HomePage).
