hi all

how can i access my HashMap (backing bean) in the jsf-page:

<t:dataTable value="#{myHashMap.myhm}" var="table">
<t:column value=""></t:column> <!-- Frage column -->
<t:column value=""></t:column> <!-- Antwort column -->
</t:dataTable>

backing bean:

public class MyHashMap {
	
public HashMap <String, String> myhm = new HashMap<String, String>();

public HashMap<String, String> getMyhm() {
		
myhm.put("Frage1", "Antwort1");
myhm.put("Frage2", "Antwort2");
myhm.put("Frage3", "Antwort3");
myhm.put("Frage4", "Antwort4");

hi mike
thanks for your answer

it works, but the jsf-page display this:

table:
[Frage1=Antwort1, Frage3=Antwort3, Frage2=Antwort2, Frage4=Antwort4]
[Frage1=Antwort1, Frage3=Antwort3, Frage2=Antwort2, Frage4=Antwort4]
[Frage1=Antwort1, Frage3=Antwort3, Frage2=Antwort2, Frage4=Antwort4]
[Frage1=Antwort1, Frage3=Antwort3, Frage2=Antwort2, Frage4=Antwort4]

my jsf-page:
<t:outputText value="table:" />
<t:dataTable value="#{myHashMap.myhmEntrySet}" var="entry">
<t:column>
<t:outputText value="#{myHashMap.myhmEntrySet}" />
</t:column>
</t:dataTable>

what is wrong?

Re: HashMap and dataTable

Posted by Mike Kienenberger <mk...@gmail.com>.

UIData components operate on ordered lists.

So the easiest thing to do would be to use something like this:

<t:dataTable value="#{myHashMap.myhmEntrySetList}" var="entry">

public List getMyhmEntrySetList() {
    return new java.util.ArrayList(myhm.entrySet());
}
