Hai guys, still working on my custom component. How do we let our custom component participate in form submission. Apparently there is no onPrepare hook for tapestry custom component. http://tapestry.apache.org/component-rendering.html.
I'm reading http://jumpstart.doublenegative.com.au/jumpstart/examples/component/subformvalidation1 example. But still haven't grasp the general gist about ProcessSubmission/ComponentAction. Calling the prepare method from process submission doesn't seems to work. Rendering the component is fine, but when submitting the page I receive the error and stack trace bellow. Any advice? Thanks. Here's my custom component setup & prepare method: private static final ProcessSubmission PROCESS_SUBMISSION = new ProcessSubmission(); // Tapestry calls afterRender() AFTER it renders any components I contain (ie. Loop). final void afterRender() { // If we are inside a form, ask FormSupport to store PROCESS_SUBMISSION in its list of actions to do on submit. // If I contain other components, their actions will already be in the list, before PROCESS_SUBMISSION. That is // because this method, afterRender(), is late in the sequence. This guarantees PROCESS_SUBMISSION will be // executed on submit AFTER the components I contain are processed (which includes their validation). if (formSupport != null) { formSupport.store(this, PROCESS_SUBMISSION); } } private static class ProcessSubmission implements ComponentAction<LoanBundleEditTabs2> { private static final long serialVersionUID = -2132279249191788845L; @Override public String toString() { return this.getClass().getSimpleName() + ".ProcessSubmission"; } @Override public void execute(LoanBundleEditTabs2 component) { component.processSubmission(); } } private void processSubmission() { // Validate. We ensured in afterRender() that the components I contain have already been validated. prepare(); } @SetupRender void setup() { prepare(); } void prepare() { Long loanApplicationId = loanApplication.getId(); loanApplicationDetail = loanApplicationDetailDao.getByApplicationId(loanApplicationId); homeAddress = loanAddressDao.getHomeAddressByApplicationId(loanApplicationId); homeAddress2 = new AddressModel(); addressCopier.copy(homeAddress, homeAddress2); mailAddress = loanAddressDao.getMailAddressByApplicationId(loanApplicationId); mailAddress2 = new AddressModel(); addressCopier.copy(mailAddress, mailAddress2); officeAddress = loanAddressDao.getOfficeAddressByApplicationId(loanApplicationId); officeAddress2 = new AddressModel(); addressCopier.copy(officeAddress, officeAddress2); } Here's the stack trace [ERROR] ioc.Registry Failure reading parameter 'source' of component common/loan/ApplicationSummary:loanbundleedittabs2.beandisplay_0.loop: Parameter 'object' of component common/loan/ApplicationSummary:loanbundleedittabs2.beandisplay_0 is bound to null.
