For Robert Scheitlin: problem with Dynamic Legend Widget 2.5

Hi Robert,

I had a strange problem with the Dynamic Legend Widget v2.5 where opening the widget immediately after opening the map led to an empty legend display. Toggling the zoom, though, would reveal the legend. After some investigation, it appeared to me that the line in the function itemrenderer_dataChangeHandler in LegendItemRenderer.mxml had an awkward comparison:

else if(((iminscale == 0 || map.scale <= imaxscale) && map.scale >= imaxscale) && layer.visible && visArr.contains(lId))

As this differed from the similar line in the function updateVisibilty, I changed the map.scale comparison in the OR from <=maxscale to <=minscale as I felt is should have been, and the problem was resolved.

Thanks,
Marc

Marc,

Thanks for catching that I will get the source code updated and re-release for 2.5

Marc,

Can you go ahead and mark your own post as the answer that way this thread does not appear in the list as unanswered?

Thanks, Robert. I thought I had set the thread to Discussion and not Question, but it ended up as a question.
