Hi Nick,
Attached is my Home.html... Home.java
The other modules are original as posted yesterday the same. I basically
specified the parameter bindings in the template at the widget definition.
The select component keeps punching back to 1 when I attempt to change. I even
added getter/setter to Home.JAVA for the parameters.
Home.JAVA
@Persist
public abstract String getTableSize();
public abstract void setTableSize(String tableSize);
@Persist
public abstract String getPagingSpan();
public abstract void setPagingSpan(String pagingSpan);
Home.HTML
<div jwcid='[EMAIL PROTECTED]:Gallery'
collectionType='ognl:@[EMAIL PROTECTED]'
component='galleryWidget'
collectionContent='collectionContent'
autoPagingContent='autoPagingContent'
tableSize='1'
pagingSpan='5'
>
I also tried specifying the parameter as a property within the JWC file and
that failed as well.
Any ideas?
Best regards

Nick,
Prior attempts to specify
tableSize='tableSize'>
inside Home.html caused NumberFormatException because the rendering cycle was
acting on the text above in my arithmetic condition.
<span jwcid='@If' condition='ognl:(index % tableSize) == 0'>
I am giving it a try now...

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
