NoSuchElementException on submit when using a Grid with a non-default model
inside a Form
-----------------------------------------------------------------------------------------
Key: TAPESTRY-2636
URL: https://issues.apache.org/jira/browse/TAPESTRY-2636
Project: Tapestry
Issue Type: Bug
Components: tapestry-core
Affects Versions: 5.0.14
Reporter: Howard M. Lewis Ship
Assignee: Howard M. Lewis Ship
Priority: Critical
Fix For: 5.0.15
When you use the add, reorder, etc. parameters of Grid, it modifies the
BeanModel uses when rendering.
Inside a Form, on Submit, the model is again read and modified inside
setupDataSource().
However, subsequent requests for the model return the unmodified model (if the
model parameter is not bound) due to the rules of how parameters behave when
not rendering. Reading the parameter when not rendering ensures that the value
is NOT cached, forcing a re-read of the binding, which means that the property
modifications are not visible.
Grid needs to have a secondary variable to store the modified model during
rendering and on Form submit.
