Component Parameters not always persisted to the end of a Heartbeat
-------------------------------------------------------------------
Key: TAP5-931
URL: https://issues.apache.org/jira/browse/TAP5-931
Project: Tapestry 5
Issue Type: Bug
Components: tapestry-core
Affects Versions: 5.1.0.5
Reporter: Leonard Lu
Priority: Minor
Odd bug. In the component class that I will attach after creating this Issue, a
parameter of type JSONObject is bound and modified during page render, then
deferred to the end of a Heartbeat. In some circumstances when the deferred
command is run, the parameter is recreated from the bound property and the
earlier changes are lost.
Circumstances when an error occurs:
1) The parameter is bound to an empty JSONObject, either new JSONObject(), or
new JSONObject("{}")
2) The parameter is given a default value of an empty JSONObject
Circumstances when an error does not occur:
1) The parameter is bound to a populated JSONObject (e.g. new
JSONObject("{property:'value'}"))
2) The parameter is bound to any literal that is coerced to a JSONObject
3) A reference to the parameter is saved in a different final variable that is
passed into the Runnable command.
