Hallo and thank you!!
Yesterday I found the "setVariable"-Method in the Environment-Class and solved
my problem in this way:
SyndFeed feed = input.build(new XmlReader(httpCon));
BeansWrapper beanWrapper = new BeansWrapper(Configuration.VERSION_2_3_25);
BeanWrapper.setExposeFields(true);
BeanModel feedObj = new BeanModel(feed, beanWrapper);
env.setVariable(name, feedObj);
It works(!), but I will change it to your idea:
<#assign feed = readFeed("http://www.spiegel.de/einestages/index.rss";)>
This looks clearer. Thank you!
Currenty I have the following problem and I am afraid that freemarker will
currently not support this:
I have one function called "a" and I have one custome derective called "b".
"a" has one paramter called "name" and "b" has a string parameter.
Now the following seems not to be possible:
<@a data="feed" markupProperty="${b("test")}"/>
The ferrmarker engine gives me a parse error and said "(" is not closed.
Is something like this possible or made i a mistake?
THANK YOU
Ingo
