If tableSize is != 0 (according to OGNL condition check) then how is OGNL
letting it get in?

I 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.

[ +/- ] 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?

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
