Hi all,
I would like have a table, where on every row will be radio select, I
was trying code below, and rendering was ok, but after submit form tapestry
5 throw null pointer.
Any ideas, please
Thanks
John
HTML:
<t:form>
<t:radiogroup t:id="radioSelectedValue">
<table t:type="grid" source="ValueNames" row="currValue">
<t:parameter name="radioPlaceCell">
<input t:type="radio" t:id="radio" value="currValue.name"/>
</t:parameter>
</table>
</t:radiogroup>
<input type="submit" value="View detail"/>
</t:form>
JAVA:
private String radioSelectedValue;
@Component
private Form _form;
@InjectPage
private ViewValueDetail _viewValueDetail;
@OnEvent(component = "viewValueDetail")
Object makeLoad()
{
_viewValueDetail.setSelectedValueName(radioSelectedValue);
return _viewValueDetail;
}
public String getRadioSelectedValue()
{
return radioSelectedValue;
}
public void setRadioSelectedValue(String value)
{
radioSelectedValue = value;
}
...other required getter and setters...
