SplitString does not completely overwrite an existing array

[TipPro]

I was surprised to learn that creating arrays from strings using SplitString does not completely overwrite an existing array.

This became an issue when I used SplitString to create arrays of various sizes in a loop.

Here is a simplified example...

<mvt:assign name="l.myStringA" value=" 'red|yellow|blue' " />
<mvt:assign name="l.myStringB" value=" 'dog|cat|horse|mouse|rabbit' " />
<mvt:assign name="l.myStringC" value=" 'sweet|sour' " />

<mvt:do file="g.Module_Library_Utilities" name="l.success" value="SplitString( l.myStringA, '|', l.settings:myArray )"/>
<mvt:foreach iterator="curNode" array="myArray" >
[&mvt:curNode;]
</mvt:foreach>

<br />

<mvt:do file="g.Module_Library_Utilities" name="l.success" value="SplitString( l.myStringB, '|', l.settings:myArray )"/>
<mvt:foreach iterator="curNode" array="myArray" >
[&mvt:curNode;]
</mvt:foreach>

<br />

<mvt:do file="g.Module_Library_Utilities" name="l.success" value="SplitString( l.myStringC, '|', l.settings:myArray )"/>
<mvt:foreach iterator="curNode" array="myArray" >
[&mvt:curNode;]
</mvt:foreach>

Would output...

[red] [yellow] [blue]
[dog] [cat] [horse] [mouse] [rabbit]
[sweet] [sour] [horse] [mouse] [rabbit]

To avoid this issue, I simply overwrite the variable "myArray" before each SplitString.
