[xwiki-devs] Error number 4001 in 4 :

Hello. I created a class and template using the Static List class property. But when I want to create a new document, the following error is shown Error number 4001 in 4: Error while parsing velocity page PMT.NewDoc Wrapped Exception: Invocation of method 'substring' in class java.lang.String threw exception java.lang.StringIndexOutOfBoundsException: String index out of range: -1 @ PMT.NewDoc4,26? I tried to use small lists and other variations but the error seems to come from an entirely different place... please help asap. regards, V. Harikrishnan Nair || Lokah Samastah sukhino bhavantu ||
