I try to use a Map-object to hold all the page variables, but
have problems to set values.
Here is my current code (which does not work):
-----------page----------------------
<component id="message" type="TextArea">
<binding name="value" expression='attribute("message")'/>
</component>
<component id="message" type="TextField">
<binding name="value" expression='attribute("subject")'/>
</component>
----------java-----------------------
HashMap attribute;
public String attribute(String sKey) {
return (String) attributes.get(sKey);
}
public void attribute(String sKey, String value) {
attributes.put(sKey, value);
}
--------------------------------------
The in-direction works, but when i submit the form
and tapestry tries to set the value i get a
InappropriateExpressionException.
Is it possible at all? If so, please can anyone tell me what i'm missing.
Kind regards,
Oliver
