Jesse Kuhnert updated TAPESTRY-339:
-----------------------------------
Fix Version: 3.0.4
Version: 3.0.3
> LinkSubmit can cause browser back button problems
> -------------------------------------------------
>
> Key: TAPESTRY-339
> URL: http://issues.apache.org/jira/browse/TAPESTRY-339
> Project: Tapestry
> Type: Bug
> Versions: 3.0.3
> Environment: Any
> Reporter: Nick Westgate
> Assignee: Jesse Kuhnert
> Priority: Minor
> Fix For: 3.0.4
>
> If LinkSubmit is mixed with other submit components in the same form,
> erroneous submits can occur from pages accessed via the browser back button.
> This happens because LinkSubmit's hidden variable is never reset.
> Suggested fix (line marked +++) in LinkSubmit.java, renderComponent method:
> // make sure the submit function is on the page (once)
> if (cycle.getAttribute(ATTRIBUTE_FUNCTION_NAME) == null)
> {
> +++ body.addInitializationScript("document." + formName +
> "._linkSubmit.value = null;");
> body.addBodyScript(
> "function submitLink(form, elementId) {
> form._linkSubmit.value = elementId; if (form.onsubmit == null ||
> form.onsubmit()) form.submit(); }");
> cycle.setAttribute(ATTRIBUTE_FUNCTION_NAME, this);
> }
> It would be great if the corrected LinkSubmit submission mechanism detail was
> factored out into a separate class, so that other submit components could be
> built using it. For example, Glen Stampoultzis's ButtonSubmit component.
