I think he may have been using @InjectObject and not @InjectState, since the exception said "....InjectObject(value=cryptoService)." It was trying to use the object provider for the "cryptoService" prefix (which isn't defined). Are you sure you had @InjectState and not @InjectObject in your source code?

The problem as described was the case: "cryptoService" vs. "CryptoService". But James is correct, this isn't an application state object, its a service that has some internal state, and should use the "threaded" service model, or should be recoded to store the internal state (the key) somewhere else. For example I would approach this problem as a factory of InputStreams and OutputStreams that perform the decoding and encoding.--

It's called a service, but you're trying to use it as an ASO (application state object). This is somewhat of a Tapestry question and should go to the tapestry user list, but I'm familiar enough with Tapestry to help you I think. Since you're using tap 4.1.x, you can just create a service point (the website docs cover this) for your CryptoService interface and Tapestry will automatically inject (or "autowire") it into your components/pages by just declaring this:
public abstract CryptoService getCryptoService();

My CryptoService adheres to my own unique interface. So I have no need to
associate or latch onto anything HLS created.
But I did try to bootstrap it into hivemind as an ASO
<contribution configuration-id="tapestry.state.ApplicationObjects">
<state-object name="cryptoService" scope="application">
<create-instance class="common.crypto.CryptoService"/>
</state-object>
</contribution>
but upon operating my annotation in java
@InjectState("cryptoService")
public abstract CryptoService getCryptoService();
The thing quits with an exception stating that the object was not formatted
[ +/- ] Exception: Error: An error occured processing annotation
@ org.apache.tapestry.annotations.InjectObject(value=cryptoService) of public
abstract common.crypto.CryptoService proto.Login.getCryptoService(): Error:
Object provider selector 'cryptoService' is not properly formatted.
But then I found other hivemind threads that talk about HiveUtils saying
that there is no way to treat any pojo like above and we should be doing
this...
<contribution configuration-id=" hiveutils.ObjectBuilderObjects">
<object name="CryptoService" cached="true"
class="common.crypto.CryptoService">
<inject name="entityService" object="service:EntityService" />
</object>
</contribution>
<contribution configuration-id="tapestry.state.ApplicationObjects">
<state-object name="cryptoService" scope="application">
<invoke-factory object="object:CryptoService" />
</state-object>
</contribution>
But that failed due to non-existent config id of some sort...
Can anyone tell me how to get my basic pojo+unique interface into hivemind?
Using tap-4.1.1
Thanks in advance
Best regards
Ken
