Hi again. I hate to interrupt the mutliple database discussion, but I
would like to ask a question regarding the original topic on this
thread.....
So, per Thiago's suggestion I tried loop with multiple form
components, and I have an issue in that if I submit one row (one form)
with invalid input (non-numeric quantity), all quantity fields get the
invalid value and show up in error (see attached). I do not display
error messages at this point yet, just trying to get forms to work. I
haven't done anything out of the ordinary, so I probably missed
something..
<table border="1">
<tr>
<th>Item #</th>
<th>Product Description</th>
<th>Usually Ships</th>
<th>Quantity</th>
<th>Price ea.</th>
<th>Extended Price</th>
<th/>
</tr>
<t:loop source="shoppingCartForDisplay" value="cartDisplayItem" index="index">
<t:form t:id="cartForm">
<tr>
<td>${cartDisplayItem.sku}</td>
<td>${cartDisplayItem.description}</td>
<td>
<t:if test="cartDisplayItem.leadTime">
${cartDisplayItem.leadTime} day(s)
<p:else>Today</p:else>
</t:if>
</td>
<td><t:textfield t:id="quantity" size="1" validate="required"
value="cartDisplayItem.quantity"/></td>
<td>${cartDisplayItem.price}</td>
<td>${cartDisplayItem.total}</td>
<td>
<t:submit t:id="update" value="message:update-value" t:context="index"/>
<t:submit t:id="remove" value="message:remove-value" t:context="index"/>
</td>
</tr>
</t:form>
</t:loop>
</table>
