I am attempting to build a navigation menu however I’m getting a NullPointerException thrown by java whenever I select an item in the menu. For example, here is the traceback.
Traceback (most recent call last): File "<event:mouseClicked>", line 8, in <module> java.lang.NullPointerException: java.lang.NullPointerException caused by NullPointerException Ignition v7.9.13 (b2019120915) Java: Oracle Corporation 1.8.0_251
The script I am using was lifted directly from the example project template. Here is the code.
if event.clickCount == 2: row = event.source.selectedItem data = event.source.data if row != -1: # Grab the window path value out of the tree view's items dataset windowPath = data.getValueAt(row, "windowPath") system.gui.messageBox(windowPath) #system.nav.swapTo(windowPath)
The system.gui.messageBox(windowPath) shows that windowPath is not being set. Is there a way to resolve this?
