Autocomplete not working in some condtion - jsf-2

Question

I am using primefaces autocomplete component with itemtip option,
after getting suggestions I am selectiing one value as a example lastname,
but I want to display in textbox both lastname and firstname of player, so tried in this way.
itemLabel="#{p.lastName} #{p.firstName} " having some space with these two .
<p:autoComplete id="watermark" value="#{backingBean.object}"
size="40" completeMethod="#{backingBean.completeholder}"
var="p"
itemLabel="#{p.lastName} #{p.firstName} " itemValue="#{p}" converter="player">
<f:facet name="itemtip">
<h:panelGrid columns="2" styleClass="cellsp-panel">
<f:facet name="header">
<p:graphicImage value="#{p.imagePath}" width="60"
height="60" />
</f:facet>
<h:outputText value="LastName " style="font-weight:bold" />
<h:outputText id="ln" value="#{p.lastName}" />
<h:outputText value="FirstName " style="font-weight:bold" />
<h:outputText id="fn" value="#{p.firstName}" />
</h:panelGrid>
</f:facet>
<p:ajax event="itemSelect" update="e,c">
</p:ajax>
</p:autoComplete>
so after selecting a suggestion, it displays lastname and firstname of player perfectly.
But one problem is created as - it creates a space in autocomplete textbox, so i need to use
backspace to remove this space so that I can search a for getting suggestions.
How can I overcome from this problem?
Also I am using watermark on autocomplete , it works only when I use single itemLabel like
itemLabel="#{p.lastName} otherwise it unable to display watermark in autocomplete.
3.Also when I use for no-case sensitive input so that user can search without case sensitive,
once I get any suggestions and still if try to type some keyworks for further filterations,
suggestions disappears,it works if I go for case sensitive by default way.
User can type players lastname or firstname , and still he needs to gets suggestion ,what modifications should I need to done in following method ?
I have stored lastname with First letter as a Capital, so I am using toUpperCase() in this way
public List completePlayer(String query) {
List suggestions = new ArrayList();
for(Player p : players) {
if(p.getlastName().startsWith(query.toUpperCase()))
suggestions.add(p);
}
return suggestions;
}
How can I overcome from this problem?

Answer 1

Your player compare is resolving to this:
Smith.startsWith("S") -> true
Smith.startsWith("SM") -> false
What you want is:
if(p.getlastName().toUpperCase().startsWith(query.toUpperCase()))
The space in your autocomplete is coming from this line:
itemLabel="#{p.lastName} #{p.firstName} " itemValue="#{p}" converter="player">
You have a space after #{p.firstName} in itemLabel before your closing quote.
As for the watermark, I don't know. I have never tried it with an autocomplete. Can you include your p:watermark tag so we can see what it is referencing?
