laxman9 Mar 13, 2012 1:49 PM

Hi i am getting property not found exception thought i have autocomplete method in my bean

public List<String> autocomplete(String prefix) {

ArrayList<String> result = new ArrayList<String>();

if ((prefix == null) || (prefix.length() == 0)) {

for (int i = 0; i < 10; i++) {

result.add(capitals.get(i).getState());

}

} else {

Iterator<Capital> iterator = capitals.iterator();

while (iterator.hasNext()) {

Capital elem = ((Capital) iterator.next());

if ((elem.getState() != null && elem.getState().toLowerCase().indexOf(prefix.toLowerCase()) == 0)

|| "".equals(prefix)) {

result.add(elem.getState());

}

return result;

}

Below is the stack trace

looks like bean class name is not correct

you declared it as 'public class AutocompleteBean'

it should be ( 'C' capital)

public class AutoCompleteBean
