[TYPO3-mvc] injectTagBuilder

[Christian Opitz]

Hi,

I developed an extension that connects formhandler and fluid [1], so 
that it's possible to use fluid-views for formhandler. With this I 
extended the form-viewHelpers with some enhancements like f.i. that 
setting the complete form to readonly makes the form elements render 
it's values instead of the inputs or that labels automatically get a 
class 'error' when the corresponding element has errors.

I managed this by injecting a parser-interceptor[2] which injected a 
custom tag builder[3] to the current node when it is inside a form and 
instanceof Tx_Fluid_ViewHelpers_Form_AbstractFormFieldViewHelper. This 
tag builder extends Tx_Fluid_Core_ViewHelper_TagBuilder, evaluates the 
label attribute and removes it before calling parent::render() and 
extracts the values when form is readonly.

Now I upgraded to 4.5 and nothing works anymore. First issue was that 
Tx_Fluid_Core_Parser_SyntaxTree_ViewHelperNode::getViewHelper was - I 
guess - renamed to getUninitializedViewHelper(). No bigger problem to 
solve that. But the second one I could not solve: There's no 
Tx_Fluid_Core_ViewHelper_TagBasedViewHelper::injectTagBuilder() anymore?

The reason why I went the way with the interceptor was that I didn't 
find a way to hook into existing view helpers without extending from 
them - has something changed on this meanwhile?
Or could I have 
Tx_Fluid_Core_ViewHelper_TagBasedViewHelper::injectTagBuilder() back 
please?^^
