this code doesnt scale... advise thanks

Hi Folks,

This blip of code doesnt scale. I was hoping for someone to offer a solution. 

Its a gallery widget in T5.4...no js

It gathers all relevent images from hibernate/mysql and renders them < 50 images and these can get bulky large ones I sized down with width height.

My code wont scale though... I receive the FORM SIZE Exceeded error which presses me to set
set JAVA_OPTS=-Dorg.mortbay.jetty.Request.maxFormContentSize=-1

within jetty or tomcat

and I eventually hit the same high water mark resulting in crashed widget controls that fail to operate.

Here is the core image handling code for the widget code.

Can anyone see something wrong ? Images are displayed everywhere. I dont see why this shouldnt work its within a form. Is my only solution to display links instead of images  because that doesnt jive with a gallery widget.

<t:pagelink t:page="Edit" context="editPageContext">     
    <t:Any t:id="imageComponentId" id="imageComponentId">

        <img
            id="ImageWidget" src="${photoLink}" alt="${currentObject}" width="200" height="160" 
            title="${currentObject.photo.fileName}"
            model="currentObject"
            image="${photoLink}"
            style="-moz-border-radius: 5px;border-radius: 5px;-moz-box-shadow: 5px 5px 5px black;-webkit-box-shadow: 5px 5px 5px black;box-shadow: 5px 5px 5px black;"
        />
        
    </t:Any>
</t:pagelink>

Thanks for any tips

Yes it is. :)

If this Loop is inside a Form and don't have any fields inside it, add  
formState="NONE". As Howard mentioned, Loop, when inside a From, by  
default stores the iterated collection in order to be able to correctly  
set the field values when the form is submitted.

<t:Loop id="foreachitem" source="currentObject" formState="NONE">

By the way:

<t:OutputRaw value="${newTableRow}"/>

Never, never, never use ${} expansions when passing parameters to Tapestry  
components. In 100% of the case, it's either wrong or useless.  
<t:OutputRaw value="newTableRow"/> is right recommended way.

I'd also suggest you to not use tables for layout, just for tabular data,  
and avoiding inline CSS, but that's off-topic. :D
