Autocompleter autofills textfield with unexpected value
-------------------------------------------------------
Key: TAPESTRY-1441
URL: https://issues.apache.org/jira/browse/TAPESTRY-1441
Project: Tapestry
Issue Type: Bug
Components: XHR/dhtml/Ajax
Affects Versions: 4.1.2
Environment: Tapestry 4.1.2 snapshot from 5-3, WinXP, Firefox 2
Reporter: Ben Dotte
After you begin typing into an Autocompleter, the dropdown appears with
possible values and the textfield attempts to autofill itself. I would assume
it is supposed to autofill with the first available value. The problem is the
text it tries to autofill with is not right if the possible values don't start
with the value entered by the user (a contains search).
As an example, say I have an autocompleter with the values "01 blah", "02
blah", "03 blah", "04 blah", and "05 blah". I type "bla" into the textfield and
wait for the dropdown to appear. When the dropdown appears, all of the possible
values appear as expected, but the textfield now says "blablah". I would not
expect "blah" to get appended to the "bla" I typed in as this is not a valid
choice.
Either the textfield should autofill with a valid value, or it shouldn't
autofill at all, like the Tacos autocompleter. (I would prefer the latter.)
Here is some code to replicate the example:
.html:
<form jwcid="@Form">
<span jwcid="[EMAIL PROTECTED]" value="ognl:curValue"
model="ognl:model" />
</form>
.java:
public abstract String getCurValue();
public IAutocompleteModel getModel()
{
final List<String> values = Arrays.asList("01 blah", "02 blah", "03
blah", "04 blah", "05 blah");
return new IAutocompleteModel()
{
public String getLabelFor(Object value)
{
return (String) value;
}
public List getValues(String filter)
{
List<String> result = new ArrayList<String>();
for (String val : values)
{
if (val.contains(filter))
{
result.add(val);
}
}
return result;
}
public Object getPrimaryKey(Object value)
{
return values.indexOf(value);
}
public Object getValue(Object primaryKey)
{
return values.get((Integer) primaryKey);
}
};
}
