- #4116
- generalize rules for `ModelMetadata` creation; minimize metadata changes when Model is updated
- down to a single special case in VDD for `Nullable<T>`
- note existing functional tests did not need to change
- remove `ViewDataDictionary(ViewDataDictionary, object)` constructor; use `new VDD<object>(source, model)`
- allow all `Model` assignments in a view component
- copy-constructed VDD in `ViewComponentContext` previously preserved the source's declared type
nits:
- do not call `virtual SetModel()` method from constructor; now mostly redundant
- logic in copy constructor and `SetModel()` is consistent but different enough to keep code separate
- add some missing doc comments
- fix doc comment property versus type confusion; never need to specify `ViewDataDictionary.` prefix
- fix a few `TemplateBuilder` comments and remove unnecessary `model: null` argument to VDD constructor
- #1485, #1487
- handle `TemplateInfo.HtmlFieldPrefix` in `ViewDataEvaluator.Eval()`
- attempt lookup in the `ViewDataDictionary` using full name then evaluate
relative `expression` against `viewData.Model`
- handle `null` or empty `expression` special case in this method (remove `throw`s)
- always pass relative `expression` name into `Eval()`
- remove `null` or empty `expression` handling from higher-level code
- in a couple of cases, special-case returned `ViewDataInfo`
- #2662
- remove incorrect guard from `DefaultHtmlGenerator.GenerateRadioButtion()`
- add doc comments for the core methods that have changed
- enable unit tests skipped due to one of above bugs
- fix one (yeah, just one) other test with incorrect expectations
- remove functional test comments about the above bugs and update expectations
nits:
- move some comments describing `ViewDataEvaluator` methods above the methods
- test additional cases _close_ to these bugs as well
for #1485
- show odd `@Html.CheckBox()`, `@Html.Hidden()` behaviour in unit tests
- show odd `@Html.TextBox()` behaviour in functional tests (templates)
for #1487
- show odd `@Html.Value()` behaviour in unit tests
- show odd `@Html.RadioButton()`, `@Html.TextArea()` behaviour in functional tests
- show lack of validation attributes for `@Html.RadioButton()`, `<select>` tag helper
for #2662
- show odd `@Html.RadioButton(string.Empty)` behaviour in functional tests
for #2664
- show failures with `@Html.ListBox()` in unit tests
nits:
- test `IHtmlHelper` methods, not extensions
- use `ViewData`, not `ViewBag` in `HtmlGeneration_FormController`
- name test methods a bit more consistently
- rename `HtmlHelperValueExtensionsTest` to `HtmlHelperValueTest`
