(v8.1.35) I have a need to iterate through multiple components within a container. Each component is an easychart and I want to be able to go through each one and perform the same script. Rather than manually call the script for each chart and having to manually add/remove calls as charts are added/removed I would like to just loop through all of the components in the container. Based on [this](https://forum.inductiveautomation.com/t/iterating-through-components-on-a-screen-through-scripting/16335) post I thought I would be able to use the `.component` object to iterate through the component list. ```auto #get the container that holds all of the charts chartsContainer = system.gui.getParentWindow(event).getComponentForPath('Root Container.Charts') #for each chart in the container, update the path to the tagPen as needed for easyChart in chartsContainer.component: Trending.historyPathConvert_MasterToEdge(easyChart) ``` I get the following error. ```auto Traceback

I used the property browser to make sure I got the correct path to the Charts container, and I also confirmed that it is a container and not a group. ---

Important caveats to note: Your current approach doesn't check if the component is actually a chart, and your current approach doesn't do a "deep" walk, in case there's any nested container that itself contains a chart. ---

You can modify this function to make it work for you - [Fetching a component's data from window and transfer that value to Translation Manager - #2 by bkarabinchak.psi](https://forum.inductiveautomation.com/t/fetching-a-components-data-from-window-and-transfer-that-value-to-translation-manager/75007/2) This does a recursive call for inner containers. ---

That's what I had that caused the error \*edit: I see I was missing the "s". Should be component **s** not `component` ---

I'll let @pturmel tell you. 😉 > [@"java import" in script](https://forum.inductiveautomation.com/t/java-import-in-script/68953/2): > > java's `getXyz()` and `setXyz(val)` are automatically mapped to jython property `xyz` via jython's internal java machinery that implements `@property`. So both the original java methods and a python-style property become available on such "NetBeans" objects. Using the property is fewer opcodes for the jython interpreter, so should be used wherever applicable. Basically, anytime in ignition you see a method with signatures `get*(), set*(), and is*()` you should prefer to use the jython property instead. So `.getComponents()` becomes `.components`. I don't believe that this happens for anything other than default getters and setters, and the standard boolean gettter `.isXyz()`
