Bill Lucy commented on MYFACES-4318:
------------------------------------
Thanks for the feedback [~lu4242]! I understand that the value of "current" in
this case doesn't have to map to the "real" backing instance. It's unfortunate
that this invalid example works with the legacy handler (and Mojarra), but I
suppose that's why the legacy handler was left available for users.
> c:forEach problem with client side state saving
> -----------------------------------------------
>
> Key: MYFACES-4318
> URL: https://issues.apache.org/jira/browse/MYFACES-4318
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 2.2.12, 2.3.6
> Reporter: Bill Lucy
> Priority: Major
> Attachments: jsf_foreach_client_state.war,
> jsf_foreach_client_state_mvn.zip
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> There appears to be a problem with c:forEach when client side state saving is
> enabled - component states are not restored correctly after a submit. For
> example, the text entered into this inputText is lost:
> {{{color:#800000}<c:forEach{color}
> {color:#ff0000}var{color}{color:#000000}={color}{color:#0000ff}"current"{color}
>
> {color:#ff0000}items{color}{color:#000000}={color}{color:#0000ff}"#\{list.items}"{color}{color:#800000}>{color}}}
> {{{color:#800000}<h:inputText{color}
> {color:#ff0000}value{color}{color:#000000}={color}{color:#0000ff}"#\{current.value}"{color}{color:#800000}/>{color}}}
> {{{color:#800000}<h:commandButton{color}
> {color:#ff0000}value{color}{color:#000000}={color}{color:#0000ff}"submit"{color}{color:#800000}/>{color}}}
> {{{color:#800000}</c:forEach>{color}}}
>
> This example works (the inputText is not lost) with server side state saving
> enabled, and it also works on Mojarra with client side state saving. I
> haven't figured out what exactly is causing this behavior yet - if anyone
> else has insight in this area I'd appreciate hints.
