  • 0

I have several debug printouts in my script with console.log(message), but no messages displayed in Console section of Firebug.

What can be a reason for this?

UPDATE 1

Neither of console.warn, console.error and console.info works.

UPDATE 2

I have a following log function:

function log(message) {
   console.error(message);
   $("#log").append(message + "<br/>");
}

so it logs both into Firebug console and DIV on page. I see that DIV logging works. Hence the control reaches the statements.

UPDATE 3

–irrelevant–

UPDATE 4

Update 3 was irrelevant: consoleBody in firebug.js was not always null. Later it was becoming valued.

But I saw that the content of consoleBody contains “div#log”. Probably it interferes with my naming…

UPDATE 5

Renaming of ID of my DIV didn’t help…

UPDATE 6

Whe I do console.log("hehe") in immediate line of firebug, it prints undefined

UPDATE 7

Looks like console.log() does not work within Liferay portlet at all; even very simple hello world portlet does not excecute this command.

    I’m not sure what’s the reason for such behaviour for 6.0 version but I have found the reason it doesn’t work in 5.2.3.

    It seems that Liferay includes Firebug Lite on my page and when I press F12 it appears at the bottom. It does interceps console method calls.

    Now I’m looking for correct way to remove the included script.

    EDIT:
    Seems like the reason for this is that I have developer mode enabled.

    set JAVA_OPTS=%JAVA_OPTS% -Dexternal-properties=portal-developer.properties
