Jesse Kuhnert closed TAPESTRY-1455.
-----------------------------------
Resolution: Cannot Reproduce
Assignee: Jesse Kuhnert
This particular thing I know works as I'm using the exact same logic in my own
project. The only difference is that I'm not getting a NumberFormatException
in my page when attempting to parse an empty "" string. ;)
p.s. You don't need submitForm = "foo" anymore, it gets wired automatically.

> Key: TAPESTRY-1455
> URL: https://issues.apache.org/jira/browse/TAPESTRY-1455
> Project: Tapestry
> Issue Type: Bug
> Components: XHR/dhtml/Ajax
> Affects Versions: 4.1.2
> Environment: Tapestry 4.1.2 snapshot from 5-9, WinXP
> Reporter: Ben Dotte
> Assigned To: Jesse Kuhnert
>
> I have an EventListener that is trying to take the input from one
> PropertySelection and update a second PropertySelection asynchronously based
> on the input from the first one. It works great in Firefox 2 but fails in
> IE7. In IE7, when I pick a value on the first dropdown, all values from the
> second dropdown disappear and a stacktrace appears on the console. I couldn't
> get it to work in IE6 either but I can't tell if it is the same problem or
> something else going on in the page.
> Here is some example code that demonstrates the problem:
> .html:
> <form jwcid="[EMAIL PROTECTED]">
> <span jwcid="[EMAIL PROTECTED]" value="ognl:selectedNumber"
> model="ognl:numberModel" />
> <br />
> <br />
> <span jwcid="[EMAIL PROTECTED]" value="ognl:selectedLetter"
> model="ognl:letterModel" />
> </form>
> .java:
> @InitialValue("1")
> public abstract Integer getSelectedNumber();
>
> public abstract String getSelectedLetter();
>
> public IPropertySelectionModel getNumberModel()
> {
> List<Integer> numbers = Arrays.asList(1, 2);
> return getBasicModel(numbers);
> }
>
> public IPropertySelectionModel getLetterModel()
> {
> if (getSelectedNumber().intValue() == 1)
> {
> List<String> letters = Arrays.asList("a", "b", "c");
> return getBasicModel(letters);
> }
> List<String> letters = Arrays.asList("d", "e", "f");
> return getBasicModel(letters);
> }
>
> private IPropertySelectionModel getBasicModel(final List items)
> {
> return new IPropertySelectionModel()
> {
> public String getLabel(int index)
> {
> return items.get(index).toString();
> }
> public Object getOption(int index)
> {
> return items.get(index);
> }
> public int getOptionCount()
> {
> return items.size();
> }
> public String getValue(int index)
> {
> return Integer.toString(index);
> }
> public boolean isDisabled(int index)
> {
> return false;
> }
> public Object translateValue(String value)
> {
> return getOption(Integer.parseInt(value));
> }
> };
> }
>
> @EventListener(targets="numbers", events="onchange", submitForm="theForm")
> public void numberSelected(IRequestCycle cycle)
> {
> try
> {
> cycle.getResponseBuilder().updateComponent("letters");
> }
> catch (Exception e)
> {
> e.printStackTrace();
> }
