How can I display a Lookup to Accounts in a ListProperty
Hello,
I have a Wrapper for a PageList. In this Wrapper there is a field called Versandpartner which is of type Account. In the VF page I cannot display the field {!lp.Versandpartner}, because then the system tells me "could not resolve the entity from apex inputfield value binding". I can display the field {!lp.Versandpartner.Name} but then it is only a pure text field and does not have the Metadata binding to Accounts. I could enter any string and don't have the magnifying glass.
My wrapper looks like this:
public with sharing class BarVerkaufLieferPosWrapper {
public Lieferscheinposition__c LieferPos {get; set;} // the record being wrapped around
public Integer LieflfdNr {get; set;}
public string stornostatus {get; set;}
public Integer Lieferscheinnr {get; set;}
public string statisticTable = null;
public Account Versandpartner {get; set;}
public Lager__c Lager {get; set;}
public string Paragraph300_302 = null;
// constructor for NEW Artikel records
public BarVerkaufLieferPosWrapper(){
LieflfdNr = 0;
stornostatus = '';
LieferPos = new Lieferscheinposition__c();
Lieferscheinnr = 1;
statisticTable = '<table><tr><td width=200> </td></tr></table>';
Versandpartner = null;
Lager = null;
Paragraph300_302 = '300';
}
// constructor used for existing Arikel records
public BarVerkaufLieferPosWrapper(Lieferscheinposition__c LP){
LiefLfdNr = 0;
stornostatus = '';
Lieferpos = LP;
Lieferscheinnr = 1;
statisticTable = '<table border=1><tr><td width=200> </td></tr></table>';
Versandpartner= null;
Lager = null;
Paragraph300_302 = '300';
}
public string getStatisticTable () {
return statisticTable;
}
}
and the lines in the VF Page:
<apex:column headerValue="Versandpartner">
<apex:actionregion immediate="True">
<apex:inputfield value="{!LP.Versandpartner.Name}">
<apex:actionsupport action="{!changedVersandpartner}" event="onchange" rerender="tabpanel,geliefert,Bedarfe,BedarfBlock,Page-Messages">
<apex:param name="VsPart" assignto="{!applyLiPoslfdNr}" value="{!LP.LieflfdNr}"/>
</apex:actionsupport>
</apex:inputfield>
</apex:actionregion>
</apex:column>
How can I change the behaviour, that this looks like a normal lookup for accounts?
Thanks in advance

of course this does mean that if you want the account name you'll have to retrieve that yourself - I wrote a blog post a while back on this at:
