Content Assist only works for C-files, but not for MITA-files

Hi  Mahalingam,

Updates: No Updates were found in available software sites.

Log: there indeed are some errors like:

!ENTRY org.eclipse.ui.workbench 4 2 2020-10-26 17:02:10.747
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".
!STACK 1
org.eclipse.core.runtime.CoreException: Executable extension definition for "class" not found.
at org.eclipse.core.internal.registry.ConfigurationElement.throwException(ConfigurationElement.java:62)

I uninstalled XDK-workbench, updated JAVA (from V8_231 to V8_271) and re-installed XDK-workbench.

Now Content Assist works  for both C-files and MITA-files.
Thanks, problem solved.

I face the same issue. For a while the conext manager worked and then it stopped. Reinstalling the SDK and Java didn't solve the issue.

Hello JanGieseler

Can you please share error log ("About XDK Workbench" -> "Installation Details" -> "Configuration" -> "View Error Log")?

Hello JanGieseler

By seeing the error log, there is no error related to MITA.

Does content assist is not working for all the MITA files or any specific MITA file?

Could you please create a new mita project and check whether content assist is working or not?

Could you please restart the xdk workbench and check whether content assist is working or not?

Could you please create a new workpsace and check whether content assist is working or not?
