[SOLVED] How to add a converter to parameterized messages in JSF 1.2?

How to add a converter to parameterized messages in JSF 1.2?

I'm looking for a way to convert my params in a parameterized text inside a JSF 1.2 xhtml page.

Let's say I have this parameterized message in my messages.properties (please ignore the stupidity of this example):

EXAMPLE_TEXT=Right now {0} Euro is {1} US-Dollar.

And I would like the output to look like this:

Right now 1 Euro is 1.3658 US-Dollar.

Then my xhtml code looks like this:

<h:outputFormat value="#{messages.EXAMPLE_TEXT}">
    <f:param value="#{backingBean.euroValue}" />
    <f:param value="#{backingBean.dollarValue}" />
</h:outputFormat>

I already have implemented a converter (let's say its ID is bigDecimalConverter) that converts numeric values to the particular formats.

My question now is: (How) can a converter be registered to the output's param values?

I imagine something like this (which unfortunately seems to not be possible):

<h:outputFormat value="#{messages.EXAMPLE_TEXT}">
    <f:param value="#{backingBean.euroValue}" converter="bigDecimalConverter" />
    <f:param value="#{backingBean.dollarValue}" converter="bigDecimalConverter" />
</h:outputFormat>

Asking google I found this thread, but it's no sufficient answer to my specific problem.

Thanks a lot in advance for any help!

Solution

You can have exact the same output with outputText:

1) Change output to <h:outputText value="#{messages.TEXT1} #{backingBean.euroValue} #{messages.TEXT2} #{backingBean.dollarValue} #{messages.TEXT3}" />

2) Create method in backing bean which return full String and call it in output text.
