All, I've been developing Lightning Components and get an error in Winter '17 whenever I try to use force:recordView or force:recordEdit: > Something has gone wrong. afterRender threw an error in > 'layout://rl-Contact-VIEW-FULL-012700000009b4BAAQ---force_highlights-_1-0-554b47494d493539522f4366576866475665533843413d3d.c' > [afterRender threw an error in 'markup://aura:expression' [afterRender > threw an error in 'markup://force:pageBlock' [afterRender threw an > error in 'markup://aura:html' [afterRender threw an error in > 'markup://aura:expression' [afterRender threw an error in > 'markup://force:pageBlockSectionView' [afterRender threw an error in > 'markup://aura:html' [afterRender threw an error in > 'markup://aura:html' [afterRender threw an error in > 'markup://aura:expression' [afterRender threw an error in > 'markup://force:pageBlockSectionRow' [afterRender threw an error in > 'markup://aura:html' [afterRender threw an error in > 'markup://aura:expression' [afterRender threw an error in > 'markup://force:pageBlockItemView' [afterRender threw an error in > 'markup://aura:if' [afterRender threw an error in > 'markup://aura:expression' [afterRender threw an error in > 'markup://aura:html' [afterRender threw an error in > 'markup://aura:html' [afterRender threw an error in 'markup://aura:if' > [afterRender threw an error in 'markup://aura:html' [afterRender threw > an error in 'markup://ui:tooltip' [Assertion Failed!: No cmp wrapper > has been set : null]]]]]]]]]]]]]]]]]]]] Failing descriptor: > {layout://rl-Contact-VIEW-FULL-012700000009b4BAAQ---force_highlights-_1-0-554b47494d493539522f4366576866475665533843413d3d.c}. > Please try again. I've noticed that the root of the error seems to be that ui:tooltip, which the Winter '17 documentation implies may no longer be supported? [Introducing Base Lightning Components - Bottom of the page][1] [1]: https://releasenotes.docs.salesforce.com/en-us/winter17/release-notes/rn_base_lightning_components.htm I've tried using them in components/apps with multiple components and I've also tried to use them on their own in an aura:application, just to test them: <aura:application extends="force:slds"> <force:recordView aura:id="details" recordId="0034E00000Az9OV"/> </aura:application> I've found that the component will work if you include type="MINI", but adding/removing "extends=force:slds" doesn't seem to make a difference, so the issue appears to be with the tooltips on the full page. Can anybody confirm if these components are currently broken?
