Problem with sortElements

[Former Member]

Hi .

I use the sortElements

Code :

<b>DefaultUnitsComparator comp;

comp = new DefaultUnitsComparator("ID");

wdContext.nodeUnitsDets().sortElements(comp);</b>

The compare method i implemented OK .

But....

I get an exception "java.lang.ArrayIndexOutOfBoundsException: 7 "

Why?( the Node is in size 7 )

Thanks

Hi, you've got a problem with your class DefaultUnitsComparator, could you paste the code here so i can help you?

Hi ,

<b>The code :</b>

<b>public</b> class DefaultUnitsComparator implements Comparator

{

String attribute;

<b>public</b> DefaultUnitsComparator(String attrib)

{

this.attribute = attrib;

}

<b>public</b> int compare(Object o1, Object o2)

{

try{

IWDNodeElement units1 = (IWDNodeElement) o1;

IWDNodeElement units2 = (IWDNodeElement) o2;

return units1.getAttributeAsText(attribute).

compareTo(units2.getAttributeAsText(attribute));

}

catch (Exception e)

{}

//arbitrary order

return 1;

}

Thanks,Faniel

Hi faniel,

If the array is in size 7, shouldn't the index be between 0 and 6 ? If so, index 7 will be out of bounds.
