------------------------------------
Summary: Missing check for IScopeAwareTextResourceProcessor for
concatenated resources
Key: WICKET-6611
URL: https://issues.apache.org/jira/browse/WICKET-6611
Project: Wicket
Issue Type: Bug
Components: wicket-core
Affects Versions: 8.1.0
Reporter: Thomas Heigl
Resource concatenation cannot be used with text compressors relying on scope
information.
I tried to use {{CssUrlReplacer}} in my application and it failed on startup
with an {{UnsupportedOperationException}} in the {{compress}} method.
In {{CssPackageResource}} we have the following code:
{code:java}
ICssCompressor compressor = getCompressor();
if (compressor != null && getCompress())
{
try
{
String charsetName = "UTF-8";
String nonCompressed = new String(processedResponse, charsetName);
String output;
if (compressor instanceof IScopeAwareTextResourceProcessor)
{
IScopeAwareTextResourceProcessor scopeAwareProcessor =
(IScopeAwareTextResourceProcessor) compressor;
output = scopeAwareProcessor.process(nonCompressed, getScope(), name);
}
else
{
output = compressor.compress(nonCompressed);
}
return output.getBytes(charsetName);
}
catch (Exception e)
{
log.error("Error while filtering content", e);
return processedResponse;
}
}{code}
In {{ConcatBundleResource}} this {{instanceof}} is missing and {{compress}} is
called directly.
{code:java}
if (getCompressor() != null)
{
String nonCompressed = new String(bytes, "UTF-8");
bytes = getCompressor().compress(nonCompressed).getBytes("UTF-8");
}{code}
