I have a valid JSP page using EL syntax. But the EL Syntax validator flags it as a problem.
Here is an isolated example. It seems to be flaggin map access operators as exceptions.
| Code: |
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>My JSP 'MyJsp.jsp' starting page</title>
</head>
<body>
This is my JSP page. <br>
This should be some valid EL
<br>
This passes validation
<br>
${'This is a string literal in EL'}
<br>
Here we extract the host property from the header. Jsp editor tells me this
is an el syntax error but it's not.
<br>
${header['host']}
<br>
Maybe it will work with double quotes
<br>
${header["host"]}
<br>
Nope it doesn't
<br>
</body>
</html>

FYI, this bug appears to still exist in MyEclipse 6.0. I get flagged with "EL Syntax Error" on the third line of the following snippet:
| Code: | <div class="form-row">
<label for="mrn">Subject's MRN:</label>
${lookupSubject.mrnNameMap["Columbia"]}
</div> |
Doesn't matter if I use single or double quotes, same as above...
Is there any way to get this looked into? It's now a year-old bug... |

delfuego,
Sorry for the delay. There are so many complexities to the EL validator and different forms to EL validation that unfortunately it's not a quick fix. We hope to improve the situation by 6.1, but again, there is a lot on our plate to do. |

OK -- the only issue I have is that you can't selectively suppress warnings like that from the JSP validator, so one incorrect validation error makes it incredibly difficult to find the *real* validation errors in large projects, since the "invalid" icon will persist on actually-valid objects. |

Understood.
It' ssomething we've looked into in the past, but wasn't cheap to implement. So we *did* add excluding specific files from the validation process though.
You could utilize that for certain EL heavy pages... |

I believe it was pushed to 7.0 for investigation, we had to work hard on getting Maven in, Hibernate/Spring/JPA updates in, JSF/Facelets editor/designer/preview updates in 6.5 and connector improvements (in addition to a bunch of other stuff). |

FWiW - This bug is still there in 7.0 (All-in-one / latest patches / WinXP).
I am seeing it with Taglib function. E.g. ${mytags:getURL( var1, "action="something", false)} shows a red X with the following notations:
EL Syntax Error
Undefined attribute name (action)
Undefined attribute name(false) |
