Hi sbalac
I will give your approach a try, but I don't think this will work since the
parameters are passed on a form submit.. i think..
In my case the parameters should be passed to the converter while rendering
the page?!
Please take a look to the standard DateTimeConverter. This Converter is
accepting attributes. Also it is possible to define attributes and
properties in Eclipse faces-config.xml Editor for converters?!
Here is an example of usage of the DateTimeConverter:
<h:outputText value="#{project.creationDate}">
<f:convertDateTime type="date" dateStyle="some style"/>
</h:outputText>
Source:
http://jsf.iatp.org.ua/converters/jsf_datetimeconverter.html
http://jsf.iatp.org.ua/converters/jsf_datetimeconverter.html
While copying the example I recognized the first time, that in that case the
tag is different!!
<f:convertDateTime>
How has this been done?
Thank you for your help!
