I try to show some values from different Primefaces "selectManyCheckbox" in a "inputText" field. The value in the inputText field is shown correctly, but the form doesn't proceed. I get no warnings or errors. For instance:

<p:selectManyCheckbox id="motorSonderBox" value="#{data.datenAnfrage.motorSonder}" style="width:400px">
    <f:selectItems value="#{data.datenAnfrage.motorSonder}" var="motorSonder" itemLabel="#{motorSonder}" itemValue="#{motorSonder}" />
<p:inputText style="width:180px" value="#{data.datenAnfrage.motorSonder}"/>

Can you help me?

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

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?

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

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

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
