Composite componente does not evaluate attributes

happy_robot Dec 7, 2011 4:33 AM

Hello *,

i've written a composite component for having an alternative in Richfaces 4 for rich:spacer .

Unfortunately the attributes and expressions are not evaluated.

The output of

<myspacer:spacer width="100" />

<h:graphicImage library="images" name="spacer.gif" width="px" />

What's going wrong???

Here the code of my component:

<code>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<composite:interface >

<composite:attribute name="width" default="0" type="java.lang.Integer"/>

<composite:attribute name="height" default="0" type="java.lang.Integer"/>

</composite:interface>

<composite:implementation>

<h:panelGroup rendered="#{cc.attrs.height > 0}">

<br/>

</h:panelGroup>

<h:graphicImage library="images" name="spacer.gif" width="#{cc.attrs.width}px" height="#{cc.attrs.height}px" />

</composite:implementation>

</html>

</code>

Thanks in advance

Daniel

Some more information:

The attributes

#{cc.attrs.width}
#{cc.attrs.height}

return consequently an empty String, the default value "0" as defined in the interface-part seems even not being set.

However

<h:outputText rendered="true" value="#{(cc.attrs.width+1)*8}=8" />

shows

8=8

on the screen. So evaluation is done, but the attribute values aren't assigned......

OMG
