Passing a value expression in composite component throws a NPE #13455

Closed glassfishrobot closed 14 years ago

Passing a value expression in composite component throws a NPE, static value works fine.

Converted the following component:

<p:columnChart value="#

{chartBean.javaee6Trends}

" var="t" xfield="#

{t.tweeter}" titleX="#javaee6" titleY="Tweets" maxY="#{chartBean.maxY}" height="200px" width="300px" live="true" refreshInterval="#{chartBean.refreshInterval}">

</p:columnChart>

to

<p:columnChart value="#{cc.attrs.trends}" var="t" xfield="#{t.tweeter}

" titleX="#

{cc.attrs.title}

" titleY="Tweets" live="true" height="300px" width="600px" refreshInterval="#

{chartBean.refreshInterval}

"> <p:chartSeries label="" value=" #

{t.tweets}

" /> </p:columnChart>

and the using page has:

<ez:columnChart trends="#

{chartBean.glassFishTrends}

" title="#glassfish"/>

This throws the following NPE:

Not sure if this NPE is caused by JSF runtime or PrimeFaces widget library.

This bug need to be fixed for the J1 keynote demo.
