Description robertmcauliffe 2008-10-31 21:38:15 UTC 
When creating an xhtml page, if there is a javascript block (within a <script> tag) which contains the < character, the
error highlighting (red squiggly line) does not show it as an error. Also putting the correct markup ('&lt;') does cause
errors to be displayed.

Note that the xhtml tested against validated as correct against the w3c validator, and the incorrect version was marked
as such (again by the w3c validator).

To replicate: create an xhtml page with the correct doctype etc.  Add a <script> tag and enter a for loop.

Example 1:
<script type="text/javascript">
  for (var i = 0; i < 10 ; i++ )
  {
  
  }
</script>


Example 2:
<script type="text/javascript">
  for (var i = 0; i &lt; 10 ; i++ )
  {
  
  }
</script>


Example 1 validates as incorrect against w3c, but correct in netbeans inline error marking. Example 2 validates as
correct against w3c, but incorrect in netbeans inline error marking.

We do not interpret the embedded javascript code now, should be easy to do in JsEmbeddingProvider.

As for the missing error, you are right, but currently we have almost no error checks for XHTML :-|

This looks like a problem with JS embedding into xhtml. Should be solved on the xhtml site.

The first sample is now correctly as erroneous - complains about the unquoted "<" char in the script.

Second issue is reproducible - needs to be fixed in JsEmbeddingProvider from javascript2.editor.

useless prototype

I created some kind of prototype, but finally I found out that it's unusable since we should be able to decode all special entities so probably some kind of better encoder class should be created. Anyway I was at least able to test out basic editor functionality with parts of created embeddings (not translatable to the original offset) and it looked to be working pretty well.
