Access localized messages in non-page/non-component class
Hi all,
just a short question after having tried to use several "infrastructure"
injections without success so far:
I have a class called "ModelSource" which returns several IPropertySelection
models to be used in forms. One of these is a userModel which shall
contain _localized_ entries defined in the application.properties file.
The problem is: How can I access these localized entries in the
non-page/non-component class "ModelSource"?
getMessages().getMessage("user_type_0") doesnt work for sure :(
Thanks!
Andreas

It works, now. I didn't see the "get" in front of UserModel,
sorry for not reading your post as carefully as needed ;)
Thanks for your help!

Thanks for this clarification/explanation! ;)

Everything ognl expression has a "context object". For example, if you
write "modelSource" in your .page file, the context object is the
page object so "modelSource" means calling getModelSource() on the
page object. To access this context object in the ognl expression,
use "#root".
This mechanism is provided by ognl. The actual page object is of
course provided by tapestry.

OK, and #root is provied by Tapestry?

|

|
| IPropertySelectionModel getUserModel(Messages messages) {

| }
Well, I both had the setter/getter methods...
But anyway this doesn't work either :(

Do I have to add something to hivemodule.xml to make this work?

<binding name="model" value="modelSource.getUserModel(messages)"/>
IPropertySelectionModel getUserModel(Messages messages) {

Well, what's the magic behind this [#root] thing/where can I find
a reference mentioning it? I tried that but I get the error

Try:

where #root means your page object. Make sure you have both getter and

Hi Kent,
thanks for your answer!

| to get a userModel:
|
| class ModelSource {
| IPropertySelectionModel getUserModel(IComponent component) {
| ...
| component.getMessages().getMessage("user_type_0");
| ...
| }
| }
Well, but the problem is, that the propertySelectionModel is
referenced directly in the .page file like this:
<component id="inputType" type="PropertySelection">
<binding name="value" value="attributes.userType"/>
<binding name="model" value="modelSource.userModel"/>
</component>
modelSource in injected with the annotation
@InjectObject("service:plattform.ModelSource")
public abstract ModelSource getModelSource();
How can I pass the component to the getUserModel()
method in this case?
Sncerly,
Andreas

I think the best way is to pass the component to it when you need
to get a userModel:
class ModelSource {
IPropertySelectionModel getUserModel(IComponent component) {
...
component.getMessages().getMessage("user_type_0");
...
