I didn't use JSP, the UI is programmatically created.
This is a part of the method which adds HtmlSelectOneRadio components to the
HtmlDataTable:
HtmlDataTable table = new HtmlDataTable();
this.form.getChildren().add(table);
table.setId(this.viewRoot.createUniqueId());
table.setVar("row");
table.setBorder(1);
table.setCellspacing("0");
table.setCellpadding("5");
// the snippet which creates the HtmlSimpleUIColumn components for the
table:
for (int i = 0; i < columns; i++) {
column[i] = new HtmlSimpleColumn();
table.getChildren().add(column[i]);
if (i == 0) {
HtmlOutputText hot = new HtmlOutputText();
hot.setId(this.viewRoot.createUniqueId());
ValueBinding vb = app.createValueBinding("#{row.matrixfragetext}");
hot.setValueBinding("value", vb);
hot.setEscape(false);
column[i].setWidth("150");
column[i].getChildren().add(hot);
} else {
String text = ((Auswahlmoeglichkeit)sortedAm.get(i - 1)).getText();
HtmlOutputText header = this.createHtmlOutputText(text, null);
column[i].setHeader(header);
HtmlRadio radio = new HtmlRadio();
radio.setId(this.viewRoot.createUniqueId());
ValueBinding vb =
app.createValueBinding("#{row.htmlSelectOneRadioId}");
radio.setValueBinding("for", vb);
radio.setIndex(i - 1);
column[i].getChildren().add(radio);
}
}
// the snippet which creates the HtmlSelectOneRadio components for each row
of the table:
List rowData = new ArrayList();
for (int i = 0; i < matrixfragetexte.length; i++) {
Matrixfragetext mft = (Matrixfragetext)matrixfragetexte[i];
HtmlSelectOneRadio radios = new HtmlSelectOneRadio(); // Tomahawk
table.getChildren().add(radios);
radios.setId(id);
radios.setLayout("spread");
radios.setRendererType("org.apache.myfaces.Radio");
radios.setConverter(new IntegerConverter());
List selectItems =
SelectItemsCreator.createSelectItemsListByAuswMglWithoutLabel(sorted
Am);
UISelectItems usi = new UISelectItems();
usi.setValue(selectItems);
radios.getChildren().add(usi);
radios.setValue(selected); // initially selected value
MatrixfrageRow row = new MatrixfrageRow();
row.setMatrixfragetext(mft.getText());
row.setHtmlSelectOneRadioId(radios.getId());
rowData.add(row);
}
table.setValue(model); // contains the rowData ArrayList
When processing the user input, the HtmlSelectOneRadio components are
located by using the findComponent() method of the UIComponent class.
This works well. Then the submitted or local value is evaluated (taking the
one which is not null), and it's always the initially selected value, no
matter what had been selected by the user.
I hope you can imagine what's going wrong...
Many thanks,
Matthias
