I have found the following problem realted to namespaces in wickect 2.0. If I have a template file like
<html xmlns:wicket="" xmlns:sherpa="http://www.isencia.com/timbuktu/sherpa";> <body> <wicket:panel> <sherpa:table cellpadding="0" cellspacing="0" wicket:id="messages"></sherpa:table> </wicket:panel> </body> </html> that I want is to transform it to <html xmlns:wicket="" xmlns:sherpa="http://www.isencia.com/timbuktu/sherpa";> <body> <table cellpadding="0" cellspacing="0" wicket:id="messages">The contents of my table dynamically generated here...</table> </body> </html> Then on my table component I do the following @Override protected void onComponentTag(ComponentTag tag) { if(tag.getNamespace().equals("sherpa")) { tag.setNamespace(null); } super.onComponentTag(tag); } to get rid of the sherpa namespace but then the generated markup is <html xmlns:wicket="" xmlns:sherpa="http://www.isencia.com/timbuktu/sherpa";> <body> <table cellpadding="0" cellspacing="0" wicket:id="messages">The contents of my table dymamically generated here...</sherpa:table> </body> </html> which is not exactly well formed XML. The same happens if instead of <sherpa:table cellpadding="0" cellspacing="0" wicket:id="messages"></sherpa:table> I write <sherpa:table cellpadding="0" cellspacing="0" wicket:id="messages"/> Am I doing something forbidden or is this a bug? After doing a bit of debugging I have found that there are to places were I have to alter the code on the class Component to get this working fine. Those are the methods final void renderClosingComponentTag(final MarkupStream markupStream, final ComponentTag openTag, final boolean renderTagOnly) { // Tag should be open tag and not openclose tag if (openTag.isOpen()) { // If we found a close tag and it closes the open tag, we're good if (markupStream.atCloseTag() && markupStream.getTag().closes(openTag)) { // Get the close tag from the stream ComponentTag closeTag = markupStream.getTag(); // If the open tag had its id changed if (openTag.getNameChanged()) { // change the id of the close tag closeTag = closeTag.mutable(); closeTag.setName(openTag.getName()); >> I HAVE TO ADD FOLLOWING CODE // change also the namespace if the name changed closeTag.setNamespace(openTag.getNamespace()); >> } // Render the close tag if (renderTagOnly == false) { renderComponentTag(closeTag); } markupStream.next(); } else { if (openTag.requiresCloseTag()) { // Missing close tag markupStream.throwMarkupException("Expected close tag for " + openTag); } } } } and public final void renderComponent(final MarkupStream markupStream) { this.markupIndex = markupStream.getCurrentIndex(); // Get mutable copy of next tag and apply the changes recorded in markupAttributes final ComponentTag openTag = markupStream.getTag(); final ComponentTag tag = openTag.mutable(); if (this.markupAttributes != null) { tag.getAttributes().putAll(this.markupAttributes.getChangeMap()); } // Call any tag handler onComponentTag(tag); // If we're an openclose tag if (!tag.isOpenClose() && !tag.isOpen()) { // We were something other than <tag> or <tag/> markupStream .throwMarkupException("Method renderComponent called on bad markup element: " + tag); } if (tag.isOpenClose() && openTag.isOpen()) { markupStream .throwMarkupException("You can not modify a open tag to open-close: " + tag); } try { // Render open tag if (getRenderBodyOnly() == false) { renderComponentTag(tag); } markupStream.next(); // Render the body only if open-body-close. Do not render if // open-close. if (tag.isOpen()) { // Render the body onComponentTagBody(markupStream, tag); } // Render close tag if (tag.isOpen()) { if (openTag.isOpen()) { renderClosingComponentTag(markupStream, tag, getRenderBodyOnly()); } else { // If a open-close tag has been to modified to be // open-body-close than a synthetic close tag must be // rendered. if (getRenderBodyOnly() == false) { // Close the manually opened panel tag. >> I HAVE TO ADD FOLLOWING CODE if(tag.getNameChanged()) getResponse().write(tag.syntheticCloseTagString()); else >> getResponse().write(openTag.syntheticCloseTagString()); } } } } catch (RuntimeException re) { if (re instanceof WicketRuntimeException || re instanceof AbortException) { throw re; } throw new WicketRuntimeException("Exception in rendering component: " + this, re); } } where the modifications I did are enclosed as >> I HAVE TO ADD FOLLOWING CODE >> I have tested on my application and it seems to work fine. Can any of the wicket mavens take a look to this? Please... And if they are fine could you include them on the trunk (or if I missunderstood it wrong just tell me which is the right way to achieve what I want!) Kind regards Ernesto
