I use primefaces 5.2 end Extention. I have component MasterDetail and in Autocomplete.
When I use Autocomplete with event selectItem I get error:
org.primefaces.application.exceptionhandler.PrimeExceptionHandler handle
SEVERE: Target Unreachable, identifier 'slownikDetail' resolved to null
javax.el.PropertyNotFoundException: Target Unreachable, identifier 'slownikDetail' resolved to null
at com.sun.el.parser.AstValue.getTarget(
at com.sun.el.parser.AstValue.setValue(
at com.sun.el.ValueExpressionImpl.setValue(
at com.sun.faces.facelets.el.TagValueExpression.setValue(
at javax.faces.component.UIInput.updateModel(
at javax.faces.component.UIInput.processUpdates(

So far when I had this problem in CommandButton I set attribute process=@this and it was solved. But in this case is problem because Autocomplete have not attribute process?

I don't have any idea. Help me, please
Primefaces 5.2

Even if this thread is old i observed this error very often. In your command component where you jump to the select level, it often helps to update the whole form / masterDetail.

Code: Select all

<p:commandButton process="@this" update="@form">
    <pe:selectDetailLevel level="2"/>
A second workaround you can try to put an empty dummy <pe:selectDetailLevel/> inside your autocomplete.

In PrimeFaces 6.1 autocomplete is also not working inside masterdetail level in case a rendered attribute is used on it or one of its parents.
Primefaces: 6.2
Primefaces-Extension: 6.2.2
OmniFaces: 3.0
Jsf: Mojarra 2.3.2
Server: Glassfish 5.0.0
