I'm not sure if this will help or not. I received this info a few days
back on adding autocomplete code to a test I'm working on:
From Dmitry:
Using autocomplete is 2-step process. See attachment below for excerpts
from TLD docs, but in short autoComplete and autoCompleteExpression must
be defined.
In order to use it, fields must be bound like this:
autoComplete="true"
autoCompleteExpression = "#{AutoCompleteBean.getOptions}"
where AutoCompleteBean is
<managed-bean>
<description>The backing bean for the field autoComplete
example</description>
<managed-bean-name>AutoCompleteBean</managed-bean-name>
<managed-bean-class>autocomplete.AutoCompleteBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
"Attribute indicating to turn on/off the autocomplete functionality of
the TextField. Autocomplete would trigger the AJAX request to the
component.
Autocomplete will submit the content of the text field for server side
processing that will be processed using JSFX partial lifecycle cycle.
Providing of autoComplete options remains responsibility of the
developer. Specifically, autoCompleteExpression needs to be set
By default autocomplete is off."
and for autoCompleteExpression :
" Use the autoCompleteExpression to specify the method that will filter
an autoCompleteExpression list, i.e. to produce new set of options to be
rendered as autoComplete prompts ( see autoCompleteExpression) . When
autoComplete mechanism is enabled ( by specifying autoComplete
attribute), autoCompleteExpression method will be called using the Ajax
mechanism in the background every time user changes the content of the
field. Note that this requires autoCompleteExpression method to perform
well. Also, it is recommended to limit number of options available to
user as the return of this method - both for usability and in order to
increase download speed.
The value of autoCompleteExpression must be an EL expression and it must
evaluate to the name of a public method that is defined by
com.sun.webui.jsf.model.AutoComplete, something like: public Options[]
getOptions(String filter) { ... } In this example, expression would look
like this: < webuijsf:textField autoComplete = "true"
autoCompleteExpression ="#{AutoCompleteBean.getOptions}"
text="#{AutoCompleteBean.text}" label = "AutoComplete" id = "tf" />
"
