Body:
I have had this problem before too. I wanted to pass my service a list of
Strings as its parameters, but when I try I get the following exception. I do
think this is a bug, too. I just totally forgot about it, because I just
worked around it to get my example working.
<configuration-point id="greetings" occurs="1..n">
<schema>
<element name="greeting">
<attribute name="pattern" required="true"/>
<rules>
<push-attribute attribute="pattern"/>
<invoke-parent method="addElement"/>
</rules>
</element>
</schema>
</configuration-point>
<contribution configuration-id="greetings">
<greeting pattern="Howdy, {0}!" />
<greeting pattern="Hello, {0}!" />
<greeting pattern="Hey, {0}!" />
</contribution>

Here is an overview of the issue:
---------------------------------------------------------------------
Key: HIVEMIND-15
Summary: hivemind fails on translating a string attribute in a string
Type: Wish
Status: Closed
Priority: Major
Resolution: CANNOT REPRODUCE
Project: HiveMind
Components:
framework
Versions:
1.0
Assignee: Howard M. Lewis Ship
Reporter: Christian Domsch
Created: Fri, 2 Jul 2004 5:46 AM

Environment: Windows 2000, Eclipse 3.0, j2sdk1.4.2
Description:
I have a configuration-point that builds a list of strings. When I build the
schema for the cp, hivemind expects a translator for an attribute. Since I want
to have Strings in my list, I don't need a translator.
Sadly the SmartTranslator fails on translating a string into a string, so I had
to write my own (very simple implementation :-). Maybe I did something wrong in
my configuration-point:
configuration-point (id=model) {
schema {
element (name=model) {
attribute (name=name required=true)
rules {
push-attribute (attribute=name)
invoke-parent (method=addElement)
}
}
}
}
contribution (configuration-id=model) {
model (name=MyModelName)
}
If this is correct, it would be a great enhancement, if hivemind would be able
to "translate" strings into strings without implementing a custom translator.
This is not very intuitive.
Greetings,
Christian Domsch
