I built a page with some pieces that I want to extract to a component. The pieces are parts of a form. I'm not sure I'm taking the proper approach. My current idea is to use delegates and blocks. My component template is:
<t:container xmlns:t="http://tapestry.apache.org/schema/tapestry_5_3.xsd"; xmlns:p="tapestry:parameter"> <t:block t:id="clientBlock"> <t:hidden t:id="clientId" value="client" /> <t:textfield t:id="clientName" value="clientName" /> <t:checkbox type="checkbox" t:id="includeInactiveClients" value="includeInactiveClients" /> </t:block> <t:block t:id="divisionBlock"> <t:hidden t:id="divisionId" value="division" /> <t:textfield t:id="divisionName" value="divisionName" /> <t:checkbox type="checkbox" t:id="includeInactiveDivisions" value="includeInactiveDivisions" /> </t:block> </t:container> Then in the actual page, I want to use it like this: <div class="control-group"> <label class="control-label"> Client: </label> <div class="controls"> <t:delegate to="block:clientBlock" /> </div> </div> And a similar block to divisionBlock. Right now I'm getting a null pointer exception from Hidden.java when I try to get it's client id. Specifically: @Import(library = { "ClientDivisionAutoComplete.js" }) public void afterRender() { JSONObject specs = new JSONObject( "clientId", "#" + clientIdField.getClientId(), "clientName", "#" + clientNameField.getClientId(), "includeInactiveClients", "#" + includeInactiveClientsField.getClientId(), "clientNameAutoCompleteUrl", componentResources.createEventLink("clientNameAutoComplete").toURI(), "divisionId", "#" + divisionId.getClientId(), "divisionName", "#" + divisionNameField.getClientId(), "includeInactiveDivisions", "#" + includeInactiveDivisionsField.getClientId(), "divisionNameAutoCompleteUrl", componentResources.createEventLink("divisionNameAutoComplete").toURI() ); javaScriptSupport.addInitializerCall("clientDivisionAutoComplete", specs); } The exception I'm getting is: Caused by: java.lang.NullPointerException at org.apache.tapestry5.corelib.components.Hidden.getClientId(Hidden.java:152) at com.starpoint.instihire.web.components.ClientDivisionAutoComplete.advised$afterRender_12ecdf1ecc23b3d1(ClientDivisionAutoComplete.java:128) at com.starpoint.instihire.web.components.ClientDivisionAutoComplete$Invocation_afterRender_12ecdf1ecc23b3d0.proceedToAdvisedMethod(Unknown Source) Is my approach wrong? This all works when I put it together in a single page, but I'm not having much luck extracting it to a component.
