How can I get All Parameters from a groovy Script?

Q&A
1

I want to get Process Parameters from a groovy Script to write them to a File but it seems they are not know if they are not included manually in the script.

I don't want to add all of them manually, I need to have a dynamic List.

I've try:

import org.bonitasoft.engine.api.APIAccessor
import org.bonitasoft.engine.bpm.parameter.ParameterCriterio
import org.bonitasoft.engine.api.ProcessManagementAPI
File file = new File("/var/tmp/out.txt")

parameters = apiAccessor.processAPI.getParameterInstances(processDefinitionId, 0, 100, ParameterCriterion.NAME_ASC)

parameters.each {
    varname = it.name
    file.append(varname + ": " + evaluate("$varname") + "\n")
}

 

This Method don't works. I have to add an access to each parameters in the script to make it works (parameters are Param1 and Param2 in the example)

import org.bonitasoft.engine.api.APIAccessor
import org.bonitasoft.engine.bpm.parameter.ParameterCriterio
import org.bonitasoft.engine.api.ProcessManagementAPI
File file = new File("/var/tmp/out.txt")

xx = Param1

xx = Param2

parameters = apiAccessor.processAPI.getParameterInstances(processDefinitionId, 0, 100, ParameterCriterion.NAME_ASC)

parameters.each {
    varname = it.name
    file.append(varname + ": " + evaluate("$varname") + "\n")
}

 

How can I get a dynamic Parameters List?

Best Regards

The method apiAccessor.processAPI.getParameterInstances(processDefinitionId, 0, 100, ParameterCriterion.NAME_ASC) does return a list of parameters for a specific processDefinitionId.

What is the error you get?

Hint, try first to just save the parameters info into a processVariable or log them in the log.

When this works fine, write them into a file.

I did the following:

import org.bonitasoft.engine.bpm.parameter.ParameterCriterion def myOutput def processWithParamsId = apiAccessor.getProcessAPI().getProcessDefinitionId("ProcessWithParams", "1.0")
def myParams = apiAccessor.getProcessAPI().getParameterInstances(processWithParamsId, 0, 10, ParameterCriterion.NAME_ASC) myParams.each {
    myOutput += it.name
    myOutput += " --- " + it.value
    myOutput += "\n"
}
return myOutput

where myOutput is mapped to a process variable and I can see the parameters names and values passed to this variable

Thank you, I just didn't saw I could get the value with it.value!

Best regards and sorry for my ignorance.
