How to GetCurrentSelections in an extension object?

[Andrea_Ghirardello]

Hi everyone,

I'm trying to retrieve the current selections in my extension.

I tried the example from QlikView Ajax JavaScript Library but when I select more than 6 values, I get a result in the form "x of y".

Could anyone please help me? Is there a method like the GetFieldSelections in desktop API?

Hi

Lets try this then (inspired by Steoel above)...

Define an "invisible" text property in the Define.xml file:

    <Text Expression="=GetCurrentSelections('',':',',',100)"/>

Make it invisible by not supplying any code for this Text input in the .qvpp file.

Then, in JavaScript, read the value of the corresponding text field:

    currentSelections = this.Layout.Text##.text;

where ## is the corresponding text number (0 for the first Text in the Definition.xml, 1 for the next and so on).

I use this technique to get the current QlikView version (<Text Expression="=QlikViewVersion()"/>) and it works fine, so this should probably work as well.

Thanks....we had come to the same conclusion.

I would suggest you use the API to do this: http://qlikcommunity.s3.amazonaws.com/misc/symbols/Qv.Document.html#GetCurrentSelections

Do you know of any limitations on this method? I tried using an expression I need as a property but I get an error. If I use the expression "=today()" it works just fine. However my expression does not work. To validate things the expression I am trying to use works fine in a textbox and if I unhide the property I still cannot set the default to my expression and things work, but I can paste it in via the properties dialog and everything works after.

So I can get my extension to work properly but I cannot default the one property to the required value and hide it without error.
