The new button action does not prompt the user to save before clearing.

If you load a robot and make changes, then click the new button the model is erased. If changes are made it should probably notify the user with the option to save before clearing.

Thanks for the report.

Possible approach for a fix: check the urdf_tree_->unsavedChanges variable in void URDFEditor::on_action_New_triggered() and invoke the appropriate 'save before exit' logic if required, instead of unconditionally clearing everything.

@gavanderhoorn @phvass Can you assign this one to me please?

[AndyZe]

I just realized this should include checking for changes before "Open," too

Making notes to myself: I couldn't build the m1 branch until "sudo apt-get install liboce-ocaf-dev"

Changes to some properties aren't being detected anymore.

Yes. That is documented on the wiki, see wiki/Development, and more specifically, the wiki/OCE-packages page.
