Safely Trimming Strings in FreeMarker (Advanced PDF Template)
Does anyone have a recommended, reliable process for trimming strings in FreeMarker?
The FreeMarker website suggests:
- substring (deprecated)
- truncate
- using string slicing expressions
truncate doesn't appear to be valid in the NetSuite version of FreeMarker
substring is valid. It says it will error if the end figure is greater than the length of the string, so I enclosed it in an if statement:
<#if item.inventorydetail?length gt 50>${item.inventorydetail?substring(0 ,49)}</#if>
which seemed to work, but strangely if I changed it to 'gt 75' and then 'substring(0 ,74)' it gave an unexpected error
I tried the slicing expression ${item.inventorydetail[0..*100]} which appeared to work 2 days ago, but yesterday started erroring randomly for no apparent reason (the same template, the same long text etc)
