v5.1.0

What's Changed

new

• initial on fx-bind provides a one-time value for newly created nodes (XForms 2.0)
• static on fx-instance asserts no binds read the instance - replacing it via submission skips the model update cycle
• create-nodes: support path comparisons in predicates (a/b = 'x', @c = /expr) - the path is created and the compared value is set
• create-nodes: support refs rooted at $default or /* - created below the document element
• create-nodes: honor bind order for node insertion, skip out-of-parent order anchors
• create-nodes: create nodes for fx-output and rebuild the model after creating nodes in a sub-tree
• JSON lenses: resolve simple axis paths (., .., *, name, with numeric predicates like *[2])
• template expressions in fx-upload label are evaluated and update on attribute change
• template expressions in labels of non-relevant elements are evaluated (for fx-control-menu on-demand controls)
• fx-include evaluates template expressions in inserted content immediately
• data-src URLs with template expressions (e.g. codes.{instance('i18n')?lang}.json) are resolved correctly

fixes

• calculate must not depend on its own node - fixes Cyclic error on full recalculation breaking new repeat rows
• rebuild keeps lens-backed (JSON) synthetic model items - controls on JSON instances (e.g. language switch) no longer lose their model item
• bind-empty-context: handle empty in-scope context in child and grandchild bindings
• create-nodes: fix default context resolution
• create-nodes: don't anchor new elements on a previous control outside the parent
• create-nodes: fix insertion for empty repeats, preserve predicate values
• fx-include waits for fx-fore readiness before handling events
• fx-insert with multi-step refs creates missing parent steps
• fx-send propagates _replacedInstanceUnbound for correct update behavior
• fx-submission with replace="instance" on a static instance only refreshes UI
• fx-control data-src handles empty nodesets gracefully, re-binds on new data
• stale instances in data-src lookups are fixed

performance

• model item lookup pre-filters binds by last step name - skips binds whose ref can't match
• initData scoped to subtree for repeat items and fx-include content
• fx-repeat builds row template from <template> instead of cloning last materialized row

chores

• new date-parts demo: sub-fore editing parts of a complex node (e.g. YYYY-MM-DD date)
• new initial.html demo
• many new and adapted tests
• updated bundle
