I decided to model T-4 examples and it still produces exception
private static final String[] tableSizeOptions = new String[] { "1", "2",
"3", "4", "5", "10", "25", "50", "100",
"500", "1000", "2500", "5000", "10000", "25000", "50000" };
private static final String[] pagingSpanOptions = new String[] { "5", "10",
"15", "20", "25" };
public IPropertySelectionModel getTableSizeModel()
{
if (tableSizeModel == null)
tableSizeModel = new StringPropertySelectionModel(tableSizeOptions);
return tableSizeModel;
}
public IPropertySelectionModel getPagingSpanModel()
{
if (pagingSpanModel == null)
pagingSpanModel = new
StringPropertySelectionModel(pagingSpanOptions);
return pagingSpanModel;
}
<component id="tableSizeSelect" type="PropertySelection">
<binding name="value" value="tableSize"/>
<binding name="model" value="tableSizeModel"/>
</component>
<component id="pagingSpanSelect" type="PropertySelection">
<binding name="value" value="pagingSpan"/>
<binding name="model" value="pagingSpanModel"/>
</component>
@Persist
public abstract String getTableSize();
@Persist
public abstract String getPagingSpan();
<select jwcid="tableSizeSelect" onchange="tapestry.form.refresh(this.form)"/>
<select jwcid="pagingSpanSelect" onchange="tapestry.form.refresh(this.form)"/>
I cannot do arithmetic on this property due to divide by zero.
So how do you set the DEFAULT VALUE of a property ? I see no support for doing
this.
I cannot use parameters because it states the parameter cannot be updated.
Please advise... thank You
