Hello, I am trying to set the cell span data of a power table in a python script like this: ```auto cell_span_headers = ["row", "column", "width", "height"] cell_span_data = [] for i in xrange(0, dataset.getRowCount(), 6): cell_span_data.append([i, "Enabled", 1, 6]) cell_span_data = system.dataset.toDataSet(cell_span_headers, cell_span_data) power_table = event.source.parent.getComponent("Power Table") setattr(power_table, "Cell Span Data", cell_span_data) ``` When I run this code I get the following error ```auto 16:48:37.640 [AWT-EventQueue-0] ERROR com.inductiveautomation.ignition.client.util.gui.ErrorUtil - Error executing script for event: actionPerformed
on component: Write L3Towers Targets to Tag. com.inductiveautomation.ignition.common.script.JythonExecException: Traceback (most recent call last): File "", line 100, in AttributeError: 'com.inductiveautomation.factorypmi.application.com' object has no attribute 'Cell Span Data' at org.python.core.Py.AttributeError(Py.java:178) at org.python.core.PyObject.noAttributeError(PyObject.java:965) at org.python.core.PyObject.object ___setattr__ (PyObject.java:3821) at org.python.core.PyObject.object ___setattr__ (PyObject.java:3792) at org.python.core.PyObject$object ___setattr___ exposer. __call__ (Unknown Source) at org.python.core.PyObjectDerived. __setattr__ (PyObjectDerived.java:1043) at com.inductiveautomation.factorypmi.application.script.PyComponentWrapper. __setattr__ (PyComponentWrapper.java:169) at org.python.core. __builtin__.setattr( __builtin__.java:1093) at org.python.core.BuiltinFunctions. __call__ ( __builtin__.java:203) at org.python.core.PyObject. __call__ (PyObject.java:498) at org.python.pycode._pyx279.f$0(:100) at org.python.pycode._pyx279.call_function() at org.python.core.PyTableCode.call(PyTableCode.java:173) at org.python.core.PyCode.call(PyCode.java:18) at org.python.core.Py.runCode(Py.java:1687) at com.inductiveautomation.ignition.common.script.ScriptManager.runCode(ScriptManager.java:788) at com.inductiveautomation.factorypmi.application.binding.action.ActionAdapter.runActions(ActionAdapter.java:206) at com.inductiveautomation.factorypmi.application.binding.action.ActionAdapter.invoke(ActionAdapter.java:299) at com.inductiveautomation.factorypmi.application.binding.action.RelayInvocationHandler.invoke(RelayInvocationHandler.java:57) at com.sun.proxy.$Proxy102.actionPerformed(Unknown Source) at java.desktop/javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at java.desktop/javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at java.desktop/javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at java.desktop/javax.swing.DefaultButtonModel.setPressed(Unknown Source) at java.desktop/javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.desktop/java.awt.Component.processMouseEvent(Unknown Source) at java.desktop/javax.swing.JComponent.processMouseEvent(Unknown Source) at java.desktop/java.awt.Component.processEvent(Unknown Source) at java.desktop/java.awt.Container.processEvent(Unknown Source) at java.desktop/java.awt.Component.dispatchEventImpl(Unknown Source) at java.desktop/java.awt.Container.dispatchEventImpl(Unknown Source) at java.desktop/java.awt.Component.dispatchEvent(Unknown Source) at java.desktop/java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.desktop/java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.desktop/java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.desktop/java.awt.Container.dispatchEventImpl(Unknown Source) at java.desktop/java.awt.Window.dispatchEventImpl(Unknown Source) at java.desktop/java.awt.Component.dispatchEvent(Unknown Source) at java.desktop/java.awt.EventQueue.dispatchEventImpl(Unknown Source) at java.desktop/java.awt.EventQueue$4.run(Unknown Source) at java.desktop/java.awt.EventQueue$4.run(Unknown Source) at java.base/java.security.AccessController.doPrivileged(Native Method) at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(Unknown Source) at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(Unknown Source) at java.desktop/java.awt.EventQueue$5.run(Unknown Source) at java.desktop/java.awt.EventQueue$5.run(Unknown Source) at java.base/java.security.AccessController.doPrivileged(Native Method) at java.base/java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(Unknown Source) at java.desktop/java.awt.EventQueue.dispatchEvent(Unknown Source) at java.desktop/java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.desktop/java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.desktop/java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.desktop/java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.desktop/java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.desktop/java.awt.EventDispatchThread.run(Unknown Source) Caused by: org.python.core.PyException: AttributeError: 'com.inductiveautomation.factorypmi.application.com' object has no attribute 'Cell Span Data' ... 55 common frames omitted ``` Is there a better way to set the cell span data of a power table? ---

Take a closer look at the proper property name: [https://docs.inductiveautomation.com/display/DOC81/Vision+-+Power+Table#VisionPowerTable-Properties](https://docs.inductiveautomation.com/display/DOC81/Vision+-+Power+Table#VisionPowerTable-Properties) { Names in the property editor are "prettied up" for the user. Hover over them to get the "scripting name", or look at the documentation. } If you get an error that says a particular property doesn't exist, you either don't have the object you think you have, or you've misunderstood/mistyped the name. Also, if you are trying to use `setattr()` to set an attribute that has a not-valid-for-python-or-java name, take that as a hint. ---

Thanks! I've been searching for the property name and didn't know where to look. That's a huge help.
