[TYPO3-mvc] How to select fluid templates (in extbase extensions) depending on the used backend layout of the current page?

[Roland]

this is weird.

i guess this could/must be a bug in:

++ Tx_Fluid_ViewHelpers_CObjectViewHelper
or
++ cObjGetSingle() of class tslib_cObj





this is my FLUID template snippet:

--- quote ---

<f:if 
condition="{f:cObject(typoscriptObjectPath:'lib.currentBackendLayoutUid')} 
== 7">
     <f:then>
         <f:render partial="TemplateForBackendLayout_7" />
     </f:then>
     <f:else>
         <f:render partial="TemplateForBackendLayout_default" />
     </f:else>
</f:if>

--- /quote ---





with this it works like expected:

--- quote ---
lib.currentBackendLayoutUid = TEXT
lib.currentBackendLayoutUid {
    data = field:backend_layout
    ifEmpty.cObject = TEXT
    ifEmpty.cObject.data = levelfield: -2, backend_layout_next_level, slide
}
--- /quote ---

debugging 
{f:cObject(typoscriptObjectPath:'lib.currentBackendLayoutUid')} in my 
FLUID template returns the current backend layout of the page. OK.





with this it does not work like expected:

--- quote ---
lib.currentBackendLayoutUid = TEXT
lib.currentBackendLayoutUid {
    field = backend_layout
    ifEmpty.cObject = TEXT
    ifEmpty.cObject.data = levelfield: -2, backend_layout_next_level, slide
}
--- /quote ---

debugging 
{f:cObject(typoscriptObjectPath:'lib.currentBackendLayoutUid')} in my 
FLUID template returns the parent's backend_layout_next_level. NOT OK.
