    Error loading javascript after installing Umbraco 4.7.1


    I'm working on an umbraco 4.7.0 project and I have upgrated it from 4.7.0 to 4.7.1

    It's worked like a charm on my localhost but I have a problem after installing it on the staging server :

    When I connect to the umbraco admin, I have the javascript error : "Jquery(xx).mask(...) : function does not exist" and any key press execute the umbraco Save function.

    The jquery mask plugin is used in umbraco 4.7.1 to add a date mask to the publish date in the property tab.

    The Jquery mask plugin is new in Umbraco 4.7.1 and is being included by "DateTimePicker.cs" with [ClientDependency(ClientDependencyType.Javascript, "MaskedInput/jquery.maskedinput-1.3.min.js", "UmbracoClient")]

    See :

    However, even if I delete on the Staging server the bin,umbraco and umbraco-client folders and replace them with the ones from my local computer (where it works) the bug is still there.

    But if I change

    <compilation defaultLanguage="c#" debug="false" batch="false" targetFramework="4.0">

    to <compilation defaultLanguage="c#" debug="true" batch="false"targetFramework="4.0">

    in the web.config THEN it works...

    Does someone understand what happened ? How can I make it works with compilation debug=true ??

    Thank you very much

    Hi. Perhaps it's the outdated client dependency cache to blame (when you set debug="true" in your web.config this cache is turned off by design). Try simply to clean the contents of the client dependency cache folder (by default it's  App_Data/TEMP/ClientDependency).

    I got a similar error, I have Umbraco 4.7.1.  On my dev server everything works just fine, however on the production server when I enter on the CMS, when I enter a key I get the action to save a document.  This produces that I can't edit the content.  On firebug I see there is an error "jQuery("#ctl00_body_ctl48").mask is not a function"  I clean up the Temp folder from umbraco and set the debug configuration on the web config as false but I didnt got any results.  If you have any ideas it will be a great help thanks.

    I have the exact same problem with 4.7.2, on production. 

    Content in text boxes cannot be edited, as key presses trigger the save function.

    I have deleted App_Data/Temp/Client_Dependency, but it still doesn't work.

    Any hints?

    Hi All,

    I have the same problem. I've tried all suggestions, and it still doesn't work.

    Any idea ?

    These are the errors I have on the Browser:


    This seems to be file related but we can't find the cause of it.

    The Version of Umbraco is .

    Any document type with a property of Form Picker doesn't work. It just "loads" as seen below:

    Can someone from Contour kindly take a serious look at this? :(

    This seems to be an issue that happens quite often.

    I've tried update the Contour package with the latest, for this Umbraco version and that didn't do the trick either.




     *forgot to mention, If I change the Form Picker Data type property, to Text String, it just works. So it really seems to be Contour related.
