T-4.1.* - PROPERTYSELECTIONDate: Wed, 10 Oct 2007 14:43:49 -0400I tried...
@Override protected void prepareForRender(IRequestCycle cycle) {
super.prepareForRender(cycle);
setCollection(loadCollection(getCollectionType())); if (getTableSize()
== null) setTableSize(tableSizeOptions[0]); if
(getPagingSpan() == null) setPagingSpan(pagingSpanOptions[0]);
}BUT I am unable to initialize the persistent property due to this
exception...An exception has occurred. You may continue by restarting the
session.[ +/- ] Exception: Error: Change to persistent property tableSize of
Home/galleryWidget has been ignored. Persistent properties may only be changed
prior to the rendering of the response page.Now arithmetic on this property is
impossible in the template and there is no way for me to even set the
parameter/property up at all.Is there a way out of this?Best regardsKen in
nashua

T-4.1.* - PROPERTYSELECTIONDate: Wed, 10 Oct 2007 14:32:08 -0400 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",

"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"/>

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...
