[jira] Commented: (WOOKIE-64) Wookie rewrites HTML start file incorrectly when injecting JavaScript: incorrectly encodes inline scripts

Scott Wilson commented on WOOKIE-64:
------------------------------------

This is a tricky one to address. One workaround is to wrap scripts in CDATA 
sections using:

                fProps.setUseCdataForScriptAndStyle(true);

And then later on reading back the file and stripping them out again (as they 
cause browser HTML parsing to fail):

                // go back and strip out the CDATA sections we wrapped our 
scripts in
                File file = new File(fStartPage.getAbsolutePath());
                String result = FileUtils.readFileToString(file);
                 String contentResult = 
result.toString().replaceAll("<!\\[CDATA\\[", "");
                 contentResult = contentResult.toString().replaceAll("\\]\\]>", 
"");
                FileUtils.writeStringToFile(file, contentResult);

I'm reluctant to commit this as a fix to the issue yet as I'm not sure it won't 
just create another problem down the line.

> When a widget package is uploaded into Wookie, the start file is injected 
> with Wookie javascripts using HTMLCleaner.
> However, where a widget start file already includes inline JavaScript, the 
> output is entity encoded; e.g.:
>                       if( window.widget.preferences["test1"]  == "pass1" &&
> Becomes:
>                       if( window.widget.preferences[&quot;test1&quot;]  == 
> "pass1" &amp;&amp;
> This breaks a lot of scripts.
> To test, use any of the test widgets at: 
> http://dev.w3.org/2006/waf/widgets-api/test-suite/
> This is probably best tackled in conjunction with WOOKIE-42
