Attached is the markup. It indicates no collision on ID's.
The actual select ID for the header Block is taken from the JWC file.
Subsequent select ID modeled for subsequent RenderBlocks of the same Block are
auto-generated.
So it remains a mystery as to WHY one is updating the other when both ID's are
unique. Does anyone have a clue for this?
Ideally I would like to synchronize on the ID's all to be the same (is this
possible) so if I change tableSize in the header Block, tableSize in the footer
Block will auto update and vice versa.

Here is more alarming feedback and it would be nice for some team mate to step
up and offer some support.
One of the reasons why myu property was not updating was because I modeled my
select components in a single block modeled by multiple renderblocks and it was
being clobbered by a RenderBlock that uses the same Block (hence multiple
RenderBlocks of the same Block, see Gallary.html).
Here is the Block...
<span jwcid='[EMAIL PROTECTED]'>
<table width='100%' border=1>
<tr>
<td width='25%' align='left' NOWRAP>
<span jwcid='@Insert' value='Table Size'/>
<select jwcid='tableSizeSelect'/>
<span jwcid='@Insert' value='Paging Span'/>
<select jwcid='pagingSpanSelect'/>
</td>
</tr>
</table>
</span>
Here is the RenderBlock
<form jwcid='[EMAIL PROTECTED]' listener='listener:onFormSubmit'>
<div jwcid='[EMAIL PROTECTED]'
block='ognl:components.autoPagingContent'/>
<div jwcid='[EMAIL PROTECTED]'
block='ognl:components.collectionContent'/>
<div jwcid='[EMAIL PROTECTED]'
block='ognl:components.autoPagingContent'/>
</form>
PROBLEM...
1. No matter what... if I change header propertySelect my property never changes
2. If I change footer propertySelect, not only does my footer propertySelect
change but my header does as well.
#2 is desired and I would like that to happen for #1 as well.
but it seems #1 is my problem as it gets clobbered by #2 regardless.
Howard can you elaborate. I apologize for the thread, mine are notoriously
known to be busy... but I put alot of heart and work into these. Looking
forward to your best.
I'd like to move onto the actual auto-paging handlers/metrics

Well I finally got something to stick...
<property name='tableSize' persist='session'/>
<property name='pagingSpan' persist='session'/>
I eliminated all references from Home.html since these parameters are self
contained inside Gallery widget... why pollute the upper level container
component and violate separation of concerns anyway.
But this solution is flakey. I change the selection and the PropertySelect
updates whacky... sometimes it changes other times it doesn't then other times
it never changes.
I am using a @Block to model the thing... and using multiple instances of that
block
<div jwcid='@RenderBlock' block='ognl:components.autoPagingContent'/>
<div jwcid='@RenderBlock' block='ognl:components.collectionContent'/>
<div jwcid='@RenderBlock' block='ognl:components.autoPagingContent'/>
autoPagingContent is the guy...
I am going to set the ID's on the following explicitly...
<td width='25%' align='left' NOWRAP>
<span jwcid='@Insert' value='Table Size'/>
<select jwcid='tableSizeSelect'/>
<span jwcid='@Insert' value='Paging Span'/>
<select jwcid='pagingSpanSelect'/>
</td>

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

'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;
}

<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
