This page is currently being revised. It might be incomplete or contain inaccuracies.
Description
Normally the view is updated from top to bottom. This usually is
not a problem, but under some circumstances the values for data
is not available until after the full view is computed. If such
values are needed before they are computed the order of
evaluation can be change using ng:eval-order
Usage
<ANY ng:eval-order="priority">
...
</ANY>
Parameters
Example
<div>TOTAL: without ng:eval-order {{ items.$sum('total') | currency }}</div>
<div ng:eval-order='LAST'>TOTAL: with ng:eval-order {{ items.$sum('total') | currency }}</div>
<table ng:init="items=[{qty:1, cost:9.99, desc:'gadget'}]">
<tr>
<td>QTY</td>
<td>Description</td>
<td>Cost</td>
