Groovy Scripting

Hi,

I am trying to learn how to use Groovy scripting.

I have found examples of scriplets on your site and I am having troubles running them...this one for example:

http://www.chemaxon.com/instantjchem/ijc_latest/docs/developer/scriptlets/create_new_field.html

I created a new script in my schema, copy-pasted the code and it gives me this error:

groovy.lang.MissingPropertyException: No such property: dataTree for class: script1331898630366715701113
    at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:50)

Same thing for the script to create a new entity.  Are these supposed to work as they are or do I need to adjust them?

Also, if I have two data trees (I have tried with either one or two) how do I specify which datatree and which entity?

Thanks

Hi Anna,

just briefly - you can create a script either for a schema or for a datatree. The examples you picked are the datatree scripts. You should copy-paste them into a script that resides under a datatree. Please read more in http://www.chemaxon.com/instantjchem/ijc_latest/docs/developer/#scripts which describes what variables are injected into a script depending on where it resides.

Cheers,
