Limitations in text fields

Hi,

I am facing a problem in connection with a geo extension, which loads boundaries in form of different points (log/latitudes). When I select a country (reduce data) everything works fine, when I clear the status (=all data) QV crashes.

As the field with the boundaries contains up to 15000 digits per location (data row), I guess it could have to do something with some internal limitations in QV. It happens only in web view and in connection with a geo extension.

Anybody has a solution/explanation how to manage this problem? I have tried it with 11.2 SR4 and 11.2 SR5 Beta.

Peter

Re: Limitations in text fields

It sounds like it's just a javascript/browser limitation.  You're trying to plot way too many points on the map.  Even if you're only trying to show 4 or 5 regions, each long/lat point that it takes to plot that region increases the load on javascript and the map.  This is why when there's a need for a large amount of points, you probably need to start looking at a server side mapping solution.

On the other hand, if all you're wanting to do is outline some countries, you could switch to using the svgReader extension.  If you want to also plot points, you could maybe find a less precise set of boundary data.  If it's using that many points to outline a region, it's probably being too exact in its drawing of boundaries.
