This could be the reason why...
@Override
protected void prepareForRender(IRequestCycle cycle)
{
super.prepareForRender(cycle);
setCollection(loadCollection(getCollectionType()));
if ( getTableSize() == null )
setTableSize(tableSizeModel.getOption(0).toString());
if ( getPagingSpan() == null )
setPagingSpan(pagingSpanModel.getOption(0).toString());
}
But I still do not know what the solution is.
@parameter or @Persist... it needs to be initialized regardless.
Can someone tell me what is going to make this guy persist across REFRESH's?
Is there a tapestry parameters/properties tech doc for dummies?

This is tapestry-101 stuff... and I am still wrestling with it.
I decided to use @Persist instead of @Parameter and now I get
An exception has occurred.

Subject: is not bound and can not be updated or BINDINGEXCEPTION ?
Date: Tue, 9 Oct 2007 16:17:29 -0400
Folks,
I am thrashing back and forth from
is not bound and can not be updated exception to a BindingException
Originally the app is runnable with
public abstract String getTableSize();
public abstract void setTableSize(String tableSize);
public abstract String getPagingSpan();
public abstract void setPagingSpan(String pagingSpan);
Then i decide to do this...
@Parameter(required = false, cache = true)
public abstract String getTableSize();
public abstract void setTableSize(String tableSize);
@Parameter(required = false, cache = true)
public abstract String getPagingSpan();
public abstract void setPagingSpan(String pagingSpan);
and I receive tableSize is not bound and can not be updated exception
So then i decide to goto the definition of the widget in the template... and
specify the parameters there in OGNL
Home.html
<div jwcid="[EMAIL PROTECTED]:Gallery"
collectionType="ognl:@[EMAIL PROTECTED]"
component="theWidget"
collectionContent="collectionContent"
autoPagingContent="autoPagingContent"
tableSize="ognl:theWidget.tableSize"
pagingSpan="ognl:theWidget.pagingSpan"
>
Now I receive a bindingexception.
Can someone set me straight here? Do I need to edit my JWC file and add the
following:
<parameter name="collectionContent"/>
I should think not... but not sure?
Can someone elaborate on whats going on with this?
Best regards
