Hi Rich,
Yep same guy, guilty as charged. This may not be the best solution, you may
get some better advice from some of the more experienced Tapestry people on
the forum, but it's the approach I used. The post I included earlier was
indeed about just ensuring a specific order was enforced in the js includes
for the ClientInfrastructure, but I have used a variation on it to include
my local version of blackbird.js, rather than the one that comes with
T5.1.0.5. The code is as follows:
AppModule.java:
public ClientInfrastructure
decorateClientInfrastructure(ClientInfrastructure original,
@InjectService("AssetSource") AssetSource assetSource) {
return new MyClientInfrastructure(original, assetSource);
}
MyClientInfrastructure.java:
public class MyClientInfrastructure implements ClientInfrastructure {
@Inject
AssetSource assetSource;
ClientInfrastructure clientInfrastructure;
List javascriptStack = new ArrayList();
@SuppressWarnings("unchecked")
public MyClientInfrastructure(ClientInfrastructure
clientInfrastructure, AssetSource assetSource) {
this.assetSource = assetSource;
this.clientInfrastructure = clientInfrastructure;
// Add jQuery assets in ahead of Prototype - IE8 was burping
otherwise, despite jQuery.noConflict being set
javascriptStack.add(assetSource.getAsset(null,
"context:/scripts/jquery-1.4.2.min.js", null));
javascriptStack.add(assetSource.getAsset(null,
"context:/scripts/jquery-ui-1.8.1.custom.min.js", null));
List assets = this.clientInfrastructure.getJavascriptStack();
for (Iterator i = assets.iterator(); i.hasNext();) {
Asset asset = (Asset) i.next();
if (!asset.toString().contains("blackbird.js")) {
javascriptStack.add(asset);
} else {
javascriptStack.add(assetSource.getAsset(null,
"context:/scripts/blackbird_1_0/blackbird.js", null));
}
}
}
public List<Asset> getJavascriptStack() {
//return clientInfrastructure.getJavascriptStack();
return javascriptStack;
}
public List<Asset> getStylesheetStack() {
return clientInfrastructure.getStylesheetStack();
}
}
I have my local blackbird.js physically located in the project under
src\main\webapp\scripts\blackbird_1_0\blackbird.js.
Obviously the jQuery ordering is not relevant to your specific problem, just
the replacement of blackbird.js is. Probably could be more
elegant/efficient, but it's just called once at startup so I wasn't too
concerned about it.
Hope this get things working for you <and I don't get chewed by the more
enlightened forum members!>.
Regards,
Jim.

Subject: Re: blackbird.js and IE breaking fixed CSS background image
Ah, thanks that seems like a start, but I'm having some issues with it.
The call to the constructor in the decorator method throws a
NullPointerException, it seems because there is an issue with the
ClientInfrastructure passed into the decorator method. Also, the logic
in your example seems to be based around having one javascript library
file supersede another in the stack order. How will this apply to
getting my CSS to work? Should I pass in a second, fixed version of the
blackbird.js to the javascriptStack after the original is contributed?
Also, how exactly is an asset referenced when adding to the
javascriptStack list, as a path like generic
assets/package/name/asset.filetype ?
I'm guessing you were the guy who mentioned the blackbird issue in the
first place since your name is also Jim. Thanks for the help so far.
Thanks,
Rich
