Re: Input Stream DownloadLink
Hi, Thanks for sharing your component with us! In the "about" section you use LoadableDetachableModel that returns InputStream. For single use this would work fine, but if you try to use this model second time in the same request then it may fail depending on the type of the InputStream because you may need to reset it. I cannot imagine now a use case where you will need to use it second time in the same request but I also see no reason to use LDM. Using AbstractReadOnlyModel looks better to me. Apart from that I think you can use "new ResourceLink(String, IResource)" for the same kind of tasks. E.g. with ByteArrayResource that either accepts its byte[] as constructor parameter or loads it dynamically by overriding #getData(). Happy New Year!

Re: Input Stream DownloadLink
Hi Martin, I found it very useful and really appreciate you contribution. I think it is definitely worth of effort, if something very similar does not already exist in wicket distribution. In that case, it would be great source of inspiration for new pull-request into wicket. Simple, short and clean description. I like that :) Good work Martin On Wed, Jan 6, 2016 at 12:16 AM, Martin Spielmann < martin.spielm...@pingunaut.com> wrote: > Hello all, > > I just published a small version of a download link which enables you to > serve > any data coming from an InputStream for download. > > https://github.com/pingunaut/wicket-stream-download-example > > I used that one in multiple projects now, so I thought it could be > interesting > for other people too. > Just wanted to hear, if there any need for this one out there before > spending > more effort for docs and error handling. > > Happy new year! > > > - > To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org > For additional commands, e-mail: users-h...@wicket.apache.org > >
Input Stream DownloadLink
Hello all, I just published a small version of a download link which enables you to serve any data coming from an InputStream for download. https://github.com/pingunaut/wicket-stream-download-example I used that one in multiple projects now, so I thought it could be interesting for other people too. Just wanted to hear, if there any need for this one out there before spending more effort for docs and error handling.

Re: Response already commited - Wicket or server?
Hi, This exception means that before the redirect there was a ServletWebResponse#write(byte[]) or ServletWebResponse#write(CharSequence) to the servlet response. Either put breakpoints in these methods or override them to add some logging to see what happens.

Response already commited - Wicket or server?
Hi, i have a problem on one client. The problem is weird. I'm getting an exception like the below *java.lang.IllegalStateException: UT010019: Response already commited* when downloading an Excel file generated by a model in a DownloadLink. But not all Excel files trigger this Exception. Only those which take longer to generate. Small and fast generated Excel files download normally. What's even more strange is that the exception is thrown when i access the app through the external domain like http://company.com/wapp but all Excel files are generated correctly when i'm throuh RDP on the server and access the app through http://localhost/wapp. It's Wicket 6.18 and WildFly 8.2.0.Final. Where to look for solutions or how to solve this? Is it an Wicket issue or do i have to look on the server side? java.lang.IllegalStateException: UT010019: Response already commited at io.undertow.servlet.spec.HttpServletResponseImpl.sendRedirect(HttpServletResponseImpl.java:173) at org.apache.wicket.protocol.http.servlet.ServletWebResponse.sendRedirect(ServletWebResponse.java:297) at org.apache.wicket.protocol.http.HeaderBufferingWebResponse.sendRedirect(HeaderBufferingWebResponse.java:117) at org.apache.wicket.request.handler.render.WebPageRenderer.redirectTo(WebPageRenderer.java:176) at org.apache.wicket.request.handler.render.WebPageRenderer.respond(WebPageRenderer.java:327) at org.apache.wicket.core.request.handler.RenderPageRequestHandler.respond(RenderPageRequestHandler.java:175) at org.apache.wicket.request.cycle.RequestCycle$HandlerExecutor.respond(RequestCycle.java:862) at org.apache.wicket.request.RequestHandlerStack.execute(RequestHandlerStack.java:64) at org.apache.wicket.request.cycle.RequestCycle.executeExceptionRequestHandler(RequestCycle.java:310) at org.apache.wicket.request.cycle.RequestCycle.executeExceptionRequestHandler(RequestCycle.java:319) at org.apache.wicket.request.cycle.RequestCycle.executeExceptionRequestHandler(RequestCycle.java:319) at org.apache.wicket.request.cycle.RequestCycle.executeExceptionRequestHandler(RequestCycle.java:319) at org.apache.wicket.request.cycle.RequestCycle.executeExceptionRequestHandler(RequestCycle.java:319) at org.apache.wicket.request.cycle.RequestCycle.executeExceptionRequestHandler(RequestCycle.java:319) at org.apache.wicket.request.cycle.RequestCycle.processRequest(RequestCycle.java:233) at org.apache.wicket.request.cycle.RequestCycle.processRequestAndDetach(RequestCycle.java:289) at org.apache.wicket.protocol.http.WicketFilter.processRequestCycle(WicketFilter.java:259) at org.apache.wicket.protocol.http.WicketFilter.processRequest(WicketFilter.java:201) at org.apache.wicket.protocol.http.WicketFilter.doFilter(WicketFilter.java:282) at io.undertow.servlet.core.ManagedFilter.doFilter(ManagedFilter.java:60) at io.undertow.servlet.handlers.FilterHandler$FilterChainImpl.doFilter(FilterHandler.java:132) at io.undertow.servlet.handlers.FilterHandler.handleRequest(FilterHandler.java:85) at io.undertow.servlet.handlers.security.ServletSecurityRoleHandler.handleRequest(ServletSecurityRoleHandler.java:61) at io.undertow.servlet.handlers.ServletDispatchingHandler.handleRequest(ServletDispatchingHandler.java:36) at org.wildfly.extension.undertow.security.SecurityContextAssociationHandler.handleRequest(SecurityContextAssociationHandler.java:78) at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:43) at io.undertow.servlet.handlers.security.SSLInformationAssociationHandler.handleRequest(SSLInformationAssociationHandler.java:131) at io.undertow.servlet.handlers.security.ServletAuthenticationCallHandler.handleRequest(ServletAuthenticationCallHandler.java:56) at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:43) at io.undertow.security.handlers.AbstractConfidentialityHandler.handleRequest(AbstractConfidentialityHandler.java:45) at io.undertow.servlet.handlers.security.ServletConfidentialityConstraintHandler.handleRequest(ServletConfidentialityConstraintHandler.java:63) at io.undertow.security.handlers.AuthenticationMechanismsHandler.handleRequest(AuthenticationMechanismsHandler.java:58) at io.undertow.servlet.handlers.security.CachedAuthenticatedSessionHandler.handleRequest(CachedAuthenticatedSessionHandler.java:70) at io.undertow.security.handlers.SecurityInitialHandler.handleRequest(SecurityInitialHandler.java:76) at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:43) at org.wildfly.extension.undertow.security.jacc.JACCContextIdHandler.handleRequest(JACCContextIdHandler.java:61) at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:43) at io.undertow.s
