transform | Tests if a transform exists | Test a spooled file extractor: ng:resourceExist('transform','demo_extract.sfe') Test an xslt transform: ng:resourceExist('transform','AddANode.xsl') Test an xent transform: ng:resourceExist('transform','sql_demo.xent') |

path
The path contains the path (including the name of the resource) to the resource from the resource root folder that should be verified. You can also use this to verify if a resource folder exists e.g. like this: ng:resourceExist('document','/Demo')
The function can e.g. be used for verifying, if a file exists before you try to use it in the workflow.
Please notice, that in version 1.9.0 the editor in the designer/workflow expects, that this function only accepts a single parameter, so you might see the error below, but this can be ignored:
