[Gvsig_english] QUESTION gvSIG 1.9 (BN 1253) -- Hoes does gvSIG reference shapefiles in ToC

[Simon Cropper (Botanicus Australia Pty Ltd)]

Hi,

When you have multiple instances of the same shapefile in the Table of 
Contents how does gvSIG know which your are referencing with the 
extensions or plug-ins?

I presume it would need to be as "ToC layer #1", "ToC layer #2", "ToC 
layer #3" rather than referencing by name as the ToC allows you to add 
multiple instances of the same shapefile.

I have had a lot of java heap errors since presenting multiple instances 
of the same shapefile in the ToC and creating separate labeling and 
symbology for each. I suspect that some subroutines don't explicitly 
reference the ToC list but rather the file name if that is possible. 
Crashes appear to centre around labeling and symbology issues. One wierd 
thing I have noted is the propensity of the "other values" option keeps 
reappearing even though I have it unchecked - particularly if I edit a 
file. That is, "other values" will be unchecked but when I edit the 
shapefile it reappears.

The question then is "Could the presence of multiple instances of the 
same file in the ToC, each with differing labeling and symbology, cause 
a memory leek?"
