Checks of features new in Neos 3.3

The checks of the metadata properties, components, attributes and directives that Neos 3.3 introduces: a cluster meets them once it starts using one of these features. See New checks by version for how to read this page, and New checks in Neos 3.3 for the checks an existing cluster can meet.

Dead letter topic of a server method

Code	Message	Level	Fix
M0100	Server method {0} uses its subscribed event "{1}" as dead letter topic, ...	Error	Give PubSubDeadLetterEventName a topic other than the subscribed event — see Publish and subscribe.
—	Inconsistent properties detected for server methods subscribing to event '{0}': followed by Server methods {0} all define a PubSubDeadLetterEventName ...	Error	Set PubSubDeadLetterEventName on only one of the server methods subscribing to the event.

Property masking

The masking options of entity, entity view and UI view properties (MaskingType, MaskingVisiblePrefixLength, MaskingVisibleSuffixLength, MaskingRegularExpression, MaskingCharacter), checked by neos generate. An entity view or UI view property is only checked for the options it declares itself. A key is also checked on a derived entity that makes an inherited masked property one of its keys.

Code	Message	Level	Fix
—	The property "{0}" cannot be masked: only String properties can be masked.	Error	Remove the masking type, or mask a String property.
—	The visible prefix and suffix lengths of the property "{0}" are only allowed with the Partial masking type.	Error	Remove MaskingVisiblePrefixLength and MaskingVisibleSuffixLength, or use the Partial masking type.
—	The visible prefix and suffix lengths of the property "{0}" cannot be negative.	Error	Set MaskingVisiblePrefixLength and MaskingVisibleSuffixLength to 0 or more.
—	The visible parts regular expression of the property "{0}" is only allowed with the Regex masking type.	Error	Remove MaskingRegularExpression, or use the Regex masking type.
—	The visible parts regular expression of the property "{0}" is invalid: {1}	Error	Set or fix MaskingRegularExpression as {1} says. Back-references, lookarounds and atomic groups are not supported.
—	The masking character of the property "{0}" is only allowed with a masking type.	Error	Remove MaskingCharacter, or set a masking type.
—	The masking character '{1}' of the property "{0}" is invalid: it must be a punctuation mark or a symbol, such as * or #.	Error	Use a punctuation mark or a symbol, such as * or #.
—	The masking character '{1}' of the property "{0}" is a separator of the {2} masking type: choose another character, such as * or #.	Error	Use a character that the format does not use as separator, such as * or #.
—	The key property "{0}" cannot be masked: keys appear in addresses, references and error messages.	Error	Remove the masking type of the key property.
—	The property "{0}" is part of the alternate key "{1}" and cannot be masked: alternate keys appear in addresses, references and error messages.	Error	Remove the masking type, or the property from the alternate key.
M0102	The property "{0}" is masked but not encrypted: the mask only hides the value in the responses, the value stays readable in the database. ...	Warning	Set IsEncrypted, or lower M0102.
—	The default grouping of the UI view "{1}" leaves out the property "{0}": its value or the label of its lookup is masked.	Warning	Remove the property from DefaultGrouping.
—	The {2} summary of the property "{0}" of the UI view "{1}" is left out: it would aggregate a masked value.	Warning	Remove the summary, or use the Count summary type.
—	The "{0}" element cannot edit the masked property "{1}": only a textbox without type or a form-field replaces its value as a whole.	Error	Bind the property to a textbox without type, or to a form-field.

Partial template slots

The slots of UI view templates (<partial-template-slot /> node, partial template type SlotContribution, Slot and Order properties), checked by neos generate.

Code	Message	Level	Fix
—	The partial template "{0}" of the UIView "{1}" is a slot contribution but does not define its slot.	Error	Set Slot on the contribution, or set its type to Standard.
—	The partial template "{0}" of the UIView "{1}" contributes to the slot "{2}", whose name is not in PascalCase.	Error	Rename the slot in PascalCase.
—	The partial template "{0}" of the UIView "{1}" is a standard partial template but defines the slot "{2}". ...	Error	Set its type to SlotContribution, or remove Slot.
—	The partial template "{0}" of the UIView "{1}" is a standard partial template but defines the order {2}. ...	Error	Remove Order, or set the type to SlotContribution.
—	The partial template "{0}" contributes to the slot "{1}", which no template of the UI view "{2}" declares.	Error	Declare the slot with a <partial-template-slot name="{1}" /> node in the UI view, or fix the slot name.
—	The slot "{0}" is declared more than once in the UI view "{1}".	Error	Keep a single <partial-template-slot /> node per slot name.
—	The slot "{0}" cannot be declared in the partial template "{1}", which itself contributes to a slot.	Error	Declare the slot in the UI view template or in a standard partial template.
—	The slot "{0}" cannot be declared inside a repeat.	Error	Move the node out of the repeat.
—	The "{0}" value of the "{1}" attribute on the "{2}" element is invalid because the name of a slot must be in PascalCase.	Error	Rename the slot in PascalCase.
—	The "{0}" element is unexpected, it will be ignored. — partial-template-slot in a UI component template	Error	Declare the slot in a UI view template.
—	The "{0}" partial template is a slot contribution: only its slot can insert it, not its name. ... — a partial-template node naming it	Error	Remove the partial-template node, or set the type of the partial template to Standard.

Style classes

Code	Message	Level	Fix
—	Invalid CSS in {0}: {1} — {1} gives the cause, such as unbalanced brackets, a missing .{class} rule or !important	Error	Fix the CSS of the Css target as the second part of the message says.
—	The name of the style class '{0}' is invalid: it must be in PascalCase, i.e. start with an uppercase letter and contain only letters and digits.	Error	Rename the style class in PascalCase: its CSS class is the kebab-case form of its name.
—	The CSS class '{1}' of the style class '{0}' is also the CSS class of the style class '{2}': ...	Error	Rename one of the style classes, so that their names give different CSS classes (UIView and UiView both give ui-view).
—	The name "{0}" is invalid: its CSS class "{1}" is reserved for the framework ...	Error	Rename the style class, so that its CSS class is not neos and does not start with neos- or wj-.
—	A style class must have at least one target.	Error	Add a target to the style class, a Css target for example.
—	The Neos target of {0} cannot be combined with another target.	Error	Keep the Neos target alone, or remove it.
—	Invalid Neos target in {0}: {1} — {1} gives the cause, such as a directive or a value that is not allowed	Error	Fix the directive as the second part of the message says.
—	The Neos target of {0} must have at least one directive.	Error	Add a directive to the Neos target, or remove it.
M0109	The color {0} of the directive {1} of {2} is not defined by the themes {3}. ...	Warning	Define the color in the listed themes, or use a color that every enabled theme of the cluster has. A theme that overrides the directive in its own Neos target is checked against the color of its override instead.
M0108	The color {0} of the directive {1} of {2} is a deprecated standard color: use {3} instead.	Warning	Use the color given by the message.

—	The theme '{0}' overrides the {2} target of the style class '{1}', which does not define this target.	Error	Add this target to the style class, or remove the override.

Style classes in UI templates

The style:classes directive applies style classes to an element: each class name written in its value is checked.

Code	Message	Level	Fix
M0058	The "{0}" class of the "{1}" attribute on the "{2}" element is invalid because it seems that the style class does not exist. ...	Warning	Fix the class name: the kebab-case form of the name of the style class (FeaturedCard gives featured-card).
M0058	The "{0}" class of the "{1}" attribute on the "{2}" element references a style class that belongs to a module this template's module does not depend on.	Warning	Add the ModuleAssociation to the module of the style class.

—	The "threshold" attribute on the "{0}" element requires the "viewport" attribute to be set to a real breakpoint tier ...	Error	Set a viewport other than extrasmall, or remove threshold — see Grid layout.

Additional data

The AllowAdditionalData entity option and the AdditionalData:StorageMode configuration key, checked by neos generate.
