Hi, There is two times an attribute named "LENGTH" in the schema of "Misure".
Attribute names in shapefile can only be 10 chararters long and OJ tries to take care that if a longer attribute must be truncated it will still get an unique name. So, cut attribute name to 8 characters, check if there are duplicates, add a numeric ending to the body for making them unique. What is exceptional is that Peppe has created a file that has duplicated and less than 10 characters long attribute names natively. OpenJUMP does not take this situation into account. But I wonder how this layer is created? It is not possible to create duplicate attribute names from the GUI. -Jukka Rahkonen- Johannes Kröger wrote: > Hey Giuseppe, > yay, little morning programming practise for me. :) > If I read it correctly it fails with any column name shorter than 8 > characters, weird how this was never catched before (or I am just on the > wrong path). > My line numbers are slightly off but I assume the following block is where it > errors for you: if (count<10) columnName = columnName.substring(0,8) + "_" + count; else columnName = columnName.substring(0,8) + count; > The hardcoded 8 is a problem here. A few lines above columnName is defined as: columnName = columnName.substring(0,Math.min(columnName.length(), 10)); Names will be truncated to a maximum of 10 characters here or stay as they are if they were <= 10 already. > Basically what seems to happen here is this: // A String with less than 8 characters String test = "1234567"; // Truncate to the shorter of its length or 10, here 7 so no truncation test = test.substring(0,Math.min(test.length(), 10)); // Extract the substring up to index 8 (including) test = test.substring(0,8); // test's highest index is 7, so it's OOB > The substring operations within the if/else need to take care of strings > shorter than 8 characters and truncate accordingly. > Cheers, Hannes > PS: SHP begone! > PPS: It will also fail rather badly if there are more than 99 identically > truncated names ;) > PPPS: Wouldn't it result in ambiguity if the truncation from 10 to 8 > characters leads to the same string of previously different names? abcdefghij and abcdefghik would both result in abcdefgh as "truncated + count" column name.
