Hi
I keep getting parse error in my javascript for loops. My less than operator seems to be interpreted as a open element. Anything wrong with my definitions here ?
I'm using the eclipse editor to deploy and have org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript referenced. I have run a number of scripts to date including loops with equality operators which all work.
This is a example.
When I deploy the above, through eclipse, this is the error log I get.
Suggestions ?

You might be able to escape < using < However, to iterate over a collection I'd recommend using for each, as in:
That eliminates the need for comparisons 🙂
for each (document in bpm_package.children) {
document.transformDocument("text/plain");
}That eliminates the need for comparisons 🙂

as you suggested works fine, thanks.
for(var i=0; i < 2;i++)
as you suggested works fine, thanks.

A processdefinition is an xml document. In an xml-document, < indicates the beginning of a tag …
Indeed: you shouldn't need to leave the spaces around < either.
If you really prefer not to see < then you can reverse the order of the numbers being compared: strictly speaking '>' should probably be written > , but as no XML element is open the parser will probably accept a raw '>' .

true, guess I assumed the parser would handle scripts differently, or not at all for that matter. Wiki examples show this syntax e.g
