Dear All,

I am attempting to append the tag alarm state to the dataSet. However, I am encountering an error message **'com.inductiveautomation.ignition.common.alarming.AlarmStateTransition'** object is not iterable

I have successfully read the alarm state of all the tags. I need to append their status to the Status column as per the attached image. Could someone kindly provide guidance on how to proceed?

Thank you

```python
storeData = []
copyData = event.source.parent.getComponent('copyData').data
print copyData

for row in range(copyData.getRowCount()): 
	tagPath = copyData.getValueAt(row, "TagName")
	configTagPath = tagPath+"/ATestMem/A/Alarms/Test Alarm A.EventState"
	configValue=system.tag.readBlocking(configTagPath)
	alarmstate = configValue[0].value
	print alarmstate
	

headers = ['TagName', 'status']
testData = []
for row in range(copyData.getRowCount()):
	testData.append([copyData.getValueAt(row, "TagName") for column in range(copyData.getColumnCount())])
event.source.parent.getComponent('storeData').data = system.dataset.toDataSet(headers, testData)

```

Can you try this and see if it works? If it doesn't work, can you show the complete error message?

```python
tagPaths = [tagPath + "/ATestMem/A/Alarms/Test Alarm A.EventState" for tagPath in event.source.parent.getComponent('copyData').data.getColumnAsList(0)]
tagValues = system.tag.readBlocking(tagPaths)
event.source.parent.getComponent('storeData').data = system.dataset.toDataSet(['TagName','status'],[[tagPath,str(tagValue.value)] for tagPath,tagValue in zip(tagPaths,system.tag.readBlocking(tagPaths))])

```

Hi,  
Its working nice. thank you.

Just want to know that; Is there an any way only shows the ''Active'' state? I don't want to display ''clear'' state

Thanks in Advance.

What do you want to show when the value isn't "Active"? Just leave it empty?

I modified @leonardo.godoi's script to:

- only read the tags once.
- only return rows with an 'Active' state.

You can then bind the visibility property to an expression:  
`len({Root Container.storeData.data}) > 0`

```python
tagPaths = [tagPath + "/ATestMem/A/Alarms/Test Alarm A.EventState" for tagPath in event.source.parent.getComponent('copyData').data.getColumnAsList(0)]
tagValues = [tag.value for tag in system.tag.readBlocking(tagPaths)]
event.source.parent.getComponent('storeData').data = system.dataset.toDataSet(['TagName','status'],[[tagPath,str(tagValue)] for tagPath,tagValue in zip(tagPaths,tagValues) if tagValue == 'Active'])

```

I have tried this code but it not fetching any data to power table.

```python
tagPaths = [tagPath + "/ATestMem/A/Alarms/Test Alarm A.EventState" for tagPath in event.source.parent.getComponent('copyData').data.getColumnAsList(0)]
tagValues = [tag.value for tag in system.tag.readBlocking(tagPaths)]
event.source.parent.getComponent('storeData').data = system.dataset.toDataSet(['TagName','status'],[[tagPath,str(tagValue)] for tagPath,tagValue in zip(tagPaths,tagValues) if tagValue == 'Active'])

```

Therefore I removed the below condition then code fetches all the active and clear alarm state. But I am interested only to show active state.

```python
if tagValue == 'Active'

```

```python
if event.propertyName == 'name':

	tagPaths = [tagPath + "/ATestMem/A/Alarms/Test Alarm A.EventState" for tagPath in event.source.parent.getComponent('copyData').data.getColumnAsList(0)]
	tagValues = [tag.value for tag in system.tag.readBlocking(tagPaths)]
	event.source.parent.getComponent('storeData').data = system.dataset.toDataSet(['TagName','status'],[[tagPath,str(tagValue)] for tagPath,tagValue in zip(tagPaths,tagValues)])

```

Any suggestion in this subject highly appreciable.

Try using an if clause in the list comprehension
