Tab don't want to close

[francois.belkorchia]

hello,

My problem lies in the closure of a Tab TabSet

I have a Tab with several TabSet which each contain ListGrid: all is well for that, I can open and close my tab

But I need to use the getRollOverCanvas of ListGrid.

My RollOverCanvas works, I can see the pictures and click on it. But when I used the RollOverCanvas , I will can not close my tab, it goes blank and remains apparent with the following error message:

WARN:Log:Error: Error calling method on NPObject.


Have you ever seen this?

I think I realized my mistake.
Indeed, in my opinion at that removing tab, there should be a call to remove the "ListGridRecord rollOverRecord" and "HLayout rollOverCanvas", but as these two are declared as attributes of my class "application" and want remove this generates an error.

Am I right?

Hello! I'm facing a similar problem, but I was no able to find out how to solve it correctly. I have a tabSet with some tabs, each tab's pane is a HStack with custom components and handlers (Stacks, Buttons, Canvas, EdgedCanvas etc.).

When I create a new "closable" empty tab (with no Pane), it closes correctly by clicking the x icon in the tab. Contrasting, when I add the pane to the tab and then I try to close it, It sends me a "Error calling method on NPObject" message.

I've tried destroing first the pane content. The error is fired on this action (destroy()).

I have no idea why it is happening and how to solve. provisionally I've put my code fragment inside a try block, but it's just ignoring the error (doesn'e solve it)

Thanks a lot!

I'm using SmartGWT 2.5
