QlikView Server - Crash when an Extension is adding

[#1]

Hi all,

I try to put an Extension on an QlikView Application in the server side.

My server running in a Windows Server 2003 SP1.

I have a simple extension like an HelloWorld.

My files are in the folder :

C:\Documents and Settings\Administrator.SERVER2003\Local Settings\Application Data\QlikTech\QlikView\Extensions\Objects\HelloWorld

I've copied HelloWorld folder in the folder :

C:\Documents and Settings\All Users\Application Data\QlikTech\QlikViewServer\Extensions\Objects

like the documentation says, and as this post says :

http://community.qlik.com/docs/DOC-1866

I open my QlikView document and switch on WebView. I drag&drop my extension and ... QlikView crash down. With no error, no Windows alert, nothing, just close.

I don't understand what I do wrong...

Here my definition.xml and my script.js :

definition.xml :

<?xml version="1.0" encoding="utf-8"?>

<ExtensionObject Label="Hello User" Description="PMO exemple">

    <Initiate Name="Chart.BgColor.ColorHex" value="#E0FFE0" />

            <Text Initial="" Expression="='Hello ' &amp; OSUser()"/>

</ExtensionObject>

script.js :

var html = "";

Qva.AddExtension('HelloWorld', function() {

    html += "<p style='text-align: center;'>"+ "---===oooOOOooo===---" +"</p>";

    html += "<p style='text-align: center;'>"+ "Hello Word" +"</p>";

    this.Element.innerHTML = html;

});

If anyone could give me a hand I shook his reconnaisant.

Have a nice day.

Patrick

I don't know if this is the problem, but you are creating a global variable called html. You probably should not do that. Try changing to:

Qva.AddExtension('HelloWorld', function() {

    var html = "";

    html += "<p style='text-align: center;'>"+ "---===oooOOOooo===---" +"</p>";

    html += "<p style='text-align: center;'>"+ "Hello Word" +"</p>";

    this.Element.innerHTML = html;

});

Hi Erik,

Thanks for your remark. Yes, it's a little error from me. But it's not the source of the problem.

But yes, if I don't reset the html variable, the body of the extension are appened each time I reload the page (not fun ).

But my problem about crahing down still there.

Best regards,

Patrick

Hi Patrick,

Is there a solution for this?

I had the same problem with Qlikview 11 installed in Windows XP system.

I tried installing the same qlikview in a Windows Vista system with some better configuration and it worked.

Is there any prerequsite installation need for extensions objects in QV?

Could you please post the qar file?

Hi,

I finally made the extension objects work. I upgraded my Internet Explorer for 7-8. And it started working.

I was trying to use the Extension Example.qar file that is coming with the 11. I tried the extension object Geo Heat map. It was crashing when I draged this object in webview.

I figured out there is some component of internet explorer that is not present. I was using IE 7. I downloaded IE 8 and installed. Then the Extension objects had no issue.

Hope this helps.

Regards,

Aswin
