Dynamic columns in editable table primefaces - jsf

Question

I have an editable table with dynamic columns. When I edit a row, all fields are displayed correctly. But when I click the 'save' icon, the value of my first element gets written to the wrong column.
Basically I have an undefined number of translation files and I want to display and edit them.
These files have content like
<entry key="contractlist_fleetmanager_status_ALL_STATUSES">All statuses</entry>
and for de
<entry key="contractlist_fleetmanager_status_ALL_STATUSES">Alle Zustände</entry>
Example I have 3 different translation files de, en and fr. The columns are as follows: en fr and de. But in the hashmap translation item, is get first de then some empty fields and then fr and en.
[de=Alle Zustände, null, null, null, null, null, null, null, null, fr=All statuses, en=All statuses, null, null, null, null, null]
When I debug and look into handleRowEdit, the selectedItem value is mixed up. The first element now has already the value of the en field in stead of the de field.
[de=All statuses, null, null, null, null, null, null, null, null, fr=All statuses, en=All statuses, null, null, null, null, null]
Is this caused by the fact that en is the first column (columns are: en fr de ) in my primefaces table?
How can I solve this?
This is my bean code
private TranslationItem selectedItem;
private List<TranslationItem> translationItems;
private List<ColumnModel> columns = new ArrayList<ColumnModel>();
public Translation() {
createDynamicColumns();
}
public String handleRowEdit(TranslationItem selectedItem) throws IOException {
setSelectedItem(selectedItem);
getLog().debug("rowedit");
return "";
}
public List<ColumnModel> getColumns() {
return columns;
}
public List<TranslationItem> getTranslationItems() throws IOException {
if (translationItems == null) {
translationItems = new ArrayList<TranslationItem>();
Properties[] props = new Properties[localeItems().length];
int i = 0;
for (String locale : localeItems()) {
FileInputStream in = new FileInputStream(SiteConfig.getInstance().getDefaultConfigPath() + File.separator
+ "language_" + locale + ".xml");
props[i] = new Properties();
props[i].loadFromXML(in);
in.close();
i++;
}
Enumeration<Object> keys = props[0].keys();
while (keys.hasMoreElements()) {
String key = (String) keys.nextElement();
i = 0;
Map<String, String> value = new LinkedHashMap<String, String>() {
#Override
public String put(String key, String value) {
return super.put(key, value);
}
};
for (String locale : localeItems()) {
value.put(locale, props[i].getProperty(key));
i++;
}
translationItems.add(new TranslationItem(key, value));
}
}
return translationItems;
}
public void createDynamicColumns() {
String columnTemplate = "";
for (String locale : localeItems()) {
columnTemplate += locale + " ";
}
String[] columnKeys = columnTemplate.split(" ");
columns.clear();
for (String columnKey : columnKeys) {
columns.add(new ColumnModel(columnKey, columnKey));
}
}
//inner class TranslationItem
public class TranslationItem {
private String key;
private Map<String, String> value;
public TranslationItem() {
}
public TranslationItem(String key, Map<String, String> value) {
this.key = key;
this.value = value;
}
public String getKey() {
return key;
}
public void setKey(String key) {
this.key = key;
}
public Map<String, String> getValue() {
return value;
}
public void setValue(Map<String, String> value) {
this.value = value;
}
public String getValueLocale(String locale) {
return value.get(locale);
}
}
//inner class ColumnModel
static public class ColumnModel implements Serializable {
private String header;
private String property;
public ColumnModel(String header, String property) {
this.header = header;
this.property = property;
}
public String getHeader() {
return header;
}
public String getProperty() {
return property;
}
}
And this is my jsf code
<p:dataTable id="translationtable" styleClass="ptable100" var="translation" value="#{adminTranslation.translationItems}" width="100%" height="200" widgetVar="translation"
emptyMessage="#{msg.all_lists_no_records_found}" editable="true" rowKey="#{translation.key}" rowIndexVar="rowIndex" selection="#{adminTranslation.selectedItem}" selectionMode="single"
resizableColumns="true" sortMode="multiple"
paginator="true" rows="20" rowsPerPageTemplate="5,10,20,50,100" paginatorTemplate="{FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} #{msg.all_lists_numberOfRowsDisplayed_label} {RowsPerPageDropdown}"
>
<p:ajax event="rowEdit" listener="#{adminTranslation.onEdit}" update="translationtable" />
<p:columns value="#{adminTranslation.columns}" headerText="#{column.header}" var="column" columnIndexVar="colIndex"
sortBy="#{translation.value[column.property]}" filterBy="#{translation.value[column.property]}" filterMatchMode="contains"
filterPosition="top" filterStyle="float:right;width: 200px;" styleClass="ui-editable-column">
<p:column >
<p:cellEditor>
<f:facet name="output"><h:outputText value="#{translation.value[column.property]}"/></f:facet>
<f:facet name="input"><h:inputText value="#{translation.value[column.property]}" styleClass="input ilarge" /></f:facet>
</p:cellEditor>
</p:column>
</p:columns>
<p:column >
<p:commandLink id="rowEditLink" actionListener="#{adminTranslation.handleRowEdit(translation)}" ajax="true" >
<p:rowEditor id="edit"/>
</p:commandLink>
</p:column>
</p:dataTable>
I use primefaces 3.2 on tomcat 7
