Custom method on container does not set custom component property

[mdemaris]

I would like to set several custom properties when a Window opens or is navigated back to.
Currently I have a script on the Window's internalFrameActivated that makes a call to a custom function on a Container.

def setValues(self):
	def handleContainer(container):
		for comp in container.getComponents():
			if comp.__class__.__name__ == 'PMILabel':
				processLabels(comp)
			
	def processLabels(label):
		try:
			setattr(label, 'myVal', 'Bonjour')
			print 'processLabels call'
		except AttributeError:
			print lalel.setPropertyValue('myVal', 'Bonjour')
		
		
	handleContainer(self)

I have four labels, each with a custom property of myVal. The custom function executes, and prints processLabels, but the label's texts remain unchanged.

The previous script used this instead of setattr: label.myVal = 'Bojnour'

What am I missing?

Turns out, it helps to bind the text property to the correct custom property!

EDIT: Ok, that worked on the test dummy, but it's not working at all in the actual project.

Same basic setup, except that I get an error stating that the custom function does not exist, specifically object has no attribute setRepeaterMinEnable

This is the call from internalFrameActivated:

system.gui.getParentWindow(event).getComponentForPath('Root Container.Container Recipe Load').setRepeaterMinEnable()

This is the function to be called:

def setRepeaterMinEnable(self):

	def processContainer(container):
		for comp in container.getComponents():

# --- If it's a Template Repeater ---
			if comp.__class__.__name__ == "TemplateRepeater":
				processTemplateRepeater(comp)
			elif hasattr(comp, 'getComponents'):
				processTemplateRepeater(comp)
				
				
	def processTemplateRepeater(repeater):
		templates = repeater.getLoadedTemplates()
		try:
			repeater.minEnable = 0
			print 'minEnable write success?'
		except:
			print 'minEnable write error'
		
processContainer(self)

And anther error stating that NameError: name 'processContainer' is not defined.

EDIT 2:
Indent problem!

Long-standing gap in the application of Ignition's PyComponentWrapper everywhere it might be needed. When jython applies default wrapping to a VisionComponent, it doesn't end up with the attributes for custom properties and custom methods. Details here:

Transaction groups triggered expression item updating when trigger is false

Ok, so I’ve been down the rabbit hole and found Ignition’s (undocumented) PyComponentWrapper. I haven’t deciphered it enough to be sure, but it seems to be invoked only for particular situations, based on the string constants in the class file (like “getComponent” and “getComponents”). To play with this, I constructed a conversion adapter like so: public class PyComponentAdapter implements PyObjectAdapter { public PyComponentAdapter() {} @Override public boolean canAdapt(Object jObj) { …

TL/DR: Install my Integration Toolkit to get fully automatic wrapping. If you cannot do that, use the PyComponentWrapper manually.
