Now I got it. It is so simple, I use not a <p:inputText but a <h:outputText. Anyway thank's a lot for help.

I can't put the Method toString() on this value because then an error comes up "Data Class member 'datenAnfrge.motorSonder.toString()' does not exist". Now I don't get this message postet above in the logfile but this one: Illegal Syntax for Set Operation

did you try to invoke the toString() method explicitly?

<p:inputtext style="width:180px" value="#{data.datenAnfrage.motorSonder.toString()}"/>

Hi Roland, Thanks for your answer, but it still doesn't work. My selectItems is a List of Strings and in my first form I use a different selectItems value "motorSonderList". By the way you can use the same list like in the value of p:selectManyCheckbox than only selected values are shown in further forms.

My inputText should concatenate the selected string from motorSonder and other values from other inputText fields. Something like that: p:inputText style="width:180px" value="#{data.datenAnfrage.motorSonder} #{data.datenAnfrage.drehzahl}" ></p:inputtext>

The following error is in the logfile: Cannot convert [M48S] of type class java.lang.String to interface java.util.List

Do you have any ideas how I can solve this problem?

Hi Gabriele,

i guess the Problem is following.

1st seltecitems.value Needs to be a list of String or objects . 2nd the value of p:selectmanycheckbox is a diffrent Attribute of the dataclass

if the select items value is a list of obect you Need to define the Attribute of the object in itemvalue and itemlabel e.g. motorSonde.id

then it should work.

you could have a look at the Designer log in log Directory of designer dir, maybe there are more Errors logged.

best reards Roland
