Behaviours Plugin - How to change the options listed in a Custom Field based on the value selected in the Components Field

Harish19

Hi Team,

We have Jira 4.4.5 and have installed the Behaviours Plugin Version 0.4.9.

We have a requirment to have a dependency between the System Field 'Components' and the custom Field ' SubComponents'.

SubComponents is a Single select list. The options displayed in the select list should depend on the value selected for the 'Component' field.

How can this be achieved using the Behaviours plugin. Please let me know how to write a server-side script if any required to achieve this feature.

Thanks in advance,

Harish.

Isn't that just this example: https://studio.plugins.atlassian.com/wiki/display/JBHV/Miscellaneous+Behaviours+Examples#MiscellaneousBehavioursExamples-Addorremoveoptionstosingleormultiselectfields ?

Hi Jamie,

Thanks for the reponse.

I have written the script for my components and subcomponents refering the example given in the link sent by you.

I have pasted the script in the 'Add server side script' option in the Behaviour plugin.

I get a compilation error as below :

"Compilation failure: startup failed: Script1.groovy: 23: unable to resolve class GenericValue @ line 23, column 16. GenericValue component = componentManager.getProjectManager().getComponent(Long.parseLong(componentId)) ^ 1 error "

The script i have written is as below :

public void setSubComponentOptions ()
{
FormField formComponent = getFieldById(fieldChanged)
FormField formSubcomponent = getFieldById("customfield_10502")
Object componentFormValue = formComponent.getFormValue()
List componentIds = []
if (componentFormValue instanceof List)
{ componentIds.addAll(componentFormValue as List)}
else {
if (componentFormValue) { componentIds.add(componentFormValue) }
}
Map fieldOptions = [:]
fieldOptions.put ("-1", "None")
for (Long componentId : componentIds)
{
try { Long.parseLong(componentId)}
catch (NumberFormatException e)
{ log.error ("Could not get component Id as Long")
return
}
GenericValue component = componentManager.getProjectManager().getComponent(Long.parseLong(componentId))
switch (component?.get("name"))
{
case "Comp 1" :fieldOptions.putAll (["Sub1":"Sub1", "Sub2":"Sub2", "Sample Sub 3":"Sample Sub 3"])
break
case "Comp 2" :fieldOptions.putAll (["Sample Sub 1":"Sample Sub 1", "Sub 2 sample":"Sub 2 sample"])
break
case "Comp 3" :fieldOptions.putAll (["N/A":"N/A"])
break

}
}
formSubcomponent.setFieldOptions (fieldOptions)

}

Please let me know if i am wrong in the script.

Also i dint not understand where the validator code is to be placed. Is it the server side script option only? i dint find the place to paste any code in the validator s option for a workflow transition.

Thanks,

Harish.

The example was for having a method in a file, if you're pasting it in then remove the "public void setSubComponentOptions ()" and closing }. Also add the imports:

import org.ofbiz.core.entity.GenericValue
import com.atlassian.core.ofbiz.util.OFBizPropertyUtils

Harish19

Hi Jamie,

I have removed the "Public void ..." as it is not a method.

Pasted the import statements just above the first line of the code , the script looks as below :

import org.ofbiz.core.entity.GenericValue
import com.atlassian.core.ofbiz.util.OFBizPropertyUtils
FormField formComponent = getFieldByName("components")
FormField formSubcomponent = getFieldById("customfield_10502")
Object componentFormValue = formComponent.getValue()
List componentIds = []
if (componentFormValue instanceof List)
{ componentIds.addAll(componentFormValue as List)}
else {
if (componentFormValue) { componentIds.add(componentFormValue) }
}
Map fieldOptions = [:]
fieldOptions.put ("-1", "None")
for (Long componentId : componentIds)
{
try { Long.parseLong(componentId)}
catch (NumberFormatException e)
{ log.error ("Could not get component Id as Long")
return
}
GenericValue component = componentManager.getProjectManager().getComponent(Long.parseLong(componentId))
switch (component?.get("name"))
{
case "Comp 1" :fieldOptions.putAll (["Sub1":"Sub1", "Sub2":"Sub2", "Sample Sub 3":"Sample Sub 3"])
break
case "Comp 2" :fieldOptions.putAll (["Sample Sub 1":"Sample Sub 1", "Sub 2 sample":"Sub 2 sample"])
break
case "Comp 3" :fieldOptions.putAll (["N/A":"N/A"])
break

}
}
formSubcomponent.setFieldOptions (fieldOptions)

There is no effect taking place with this script.

The options which were defined in the Field configuration for the subcomponent field are all disabled, as the options are dynamically defined in the script.

The Components field is a multi select rendered.

Do i have to enable the Behaviours Plugin through the 'User Installed Plugins' options.

When i click on the Behaviour Plugin under 'User Installed Plugins:" i do not find any Enable/Disable, Uninstall otpions. How can i enable or disable the plugin.

Your response is highly appriciated.

Thanks,

harish.

Same problem here that non of my subcomponents are changed when I choose the initial component. Did you eventually solve your issue?

Bryan Karsh

Hi,

I'm also getting similar problem (script pasted in seems to execute fine, but despite choosing component, subcomponent is not updated from "None") -- note, field for subcomponent is a multiselect list, populated with values you mentioned. custom field is associated with project, and shows all values when behavior is not turned on. When behavior is turned on, the 'None' value displays.

Any tips appreciated. I am running Jira 5.2.6, and most recent behavior plugin.

import org.ofbiz.core.entity.GenericValue
    import com.atlassian.core.ofbiz.util.OFBizPropertyUtils
    
    FormField formComponent = getFieldById(fieldChanged)
    FormField formSubcomponent = getFieldByName ("Subcomponent")
 
    Object componentFormValue = formComponent.getFormValue()
    List componentIds = []
 
    if (componentFormValue instanceof List) {
        componentIds.addAll(componentFormValue as List)
    }
    else {
        // could be an empty string if all components are deselected
        if (componentFormValue) {
            componentIds.add(componentFormValue)
        }
    }
 
    Map fieldOptions = [:]
    fieldOptions.put ("-1", "None")
 
    for (Long componentId : componentIds) {
        try {
            Long.parseLong(componentId)
        } catch (NumberFormatException e) {
            log.error ("Could not get component Id as Long")
            return
        }
 
        GenericValue component = componentManager.getProjectManager().getComponent(Long.parseLong(componentId))
 
        switch (component?.get("name")) {
            case "Component 1" :
                fieldOptions.putAll (["Lemons":"Lemons", "Oranges":"Oranges"])
                break
 
            case "Component 2" :
                fieldOptions.putAll (["Spinach":"Spinach", "Celery":"Celery"])
                break
 
        }
    }
    formSubcomponent.setFieldOptions (fieldOptions)

Same type of errors in my log as well!

Marco Colageo1

Same problem too.

By commenting the codelines below I've got the subComponent field set to None.

for (Long componentId : componentIds) {
        /*try {
            Long.parseLong(componentId)
        } catch (NumberFormatException e) {
            log.error ("Could not get component Id as Long")
            return
        }*/
 
       .......

So I assume that the try/catch gives an exception. Is there a way to rewrite this step to try something different?

Cheers

Marco

Hello everyone.

I have the same problem.
Debug "1" is shown. Debug "2" not... Can anyone please help me.

Thanks in advance.

JamieA

Not sure what you mean by "debug 2". Are you saying it doesn't print "2" from "log.error("2")" ?

PetraPensky

Yeah. It doesn't print the "2".

JamieA

That could mean componentIds is empty? If you don't get that there should be some other messages, maybe an error stack trace?

Radha Khullar

Thanks it was a great help.

I was able to write behaviour plugin based on the above shared code.

Below is the working code for me in case someone needs.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.bc.project.component.ProjectComponent

def customFieldManager = ComponentAccessor.getCustomFieldManager()

def selectList1 = getFieldById(fieldChanged)
def selectList2 = getFieldByName("Sub-component")

def selectList1Val = selectList1.getValue()
Map fieldOptions = [:]
fieldOptions.put ("-1", "None")

selectList1Val.each{
def selectListname = it.getAt("name")

switch (selectListname){
case "Comp 1" :fieldOptions.putAll (["22601":"Sub1", "22602":"Sub2", "22603":"Sample Sub 3"])
break
case "Comp 2" :fieldOptions.putAll (["22604":"Sample Sub 1", "22605":"Sub 2 sample"])
break
}

}
selectList2.setFieldOptions (fieldOptions)

The numbers 22601 through 22605 are the option ids that can be retrieved by hover on Edit link of option value under "Edit Options for Custom Field"
