Leonardo Uribe commented on MYFACES-2464:
-----------------------------------------
Really in that case we need "four", one per each stage.
The advantage is these resources are not wrapped by
ValueExpressionFilterInputStream anymore, but we have to set "Last-Modified"
header in the same way as for css resources. So, if the app is restarted, the
javascript is downloaded again. Otherwise, if the user changes the project
stage value on server, this one will not be detected by the client.
> Find a way to do not use ELExpressions on jsf.js for getProjectStage

> Key: MYFACES-2464
> URL: https://issues.apache.org/jira/browse/MYFACES-2464
> Project: MyFaces Core
> Issue Type: Improvement
> Components: JSR-314
> Affects Versions: 2.0.0-alpha
> Reporter: Leonardo Uribe
>
> After do some tests, it was detected RI 2.0.1 uses other strategy to do that.
> Instead using an ELExpression to retrieve the project stage when jsf.js is
> send, uses a combination of javascript and rewrite request path to send this
> value. If the application is not on Production stage the url written by the
> script looks like this:
> <script type="text/javascript"
> src="/test-webapp/javax.faces.resource/jsf.js.jsf?ln=javax.faces&stage=Development">
> note "ln" is written on ResourceImpl.getRequestPath(), so I suppose stage is
> set there too.
> The problem is the javascript part. I don't know how to retrieve it with some
> javascript algorithm in getProjectStage. Note this param is written on the
> attribute src, and no ajax request should be triggered for retrieve this
> value.
> Right now, the solution committed MYFACES-2460 just deal with this file like
> any other css file that could contain EL Expressions (these expressions are
> "application scope", in other words, its value is the same all time in the
> application life).
> Suggestions are welcome.
