php - TYPO3 Femanager Template placeholder condition -

i have quite simple problem. want add star femanager inputfield if required.

i tried:

<f:form.textarea             id="femanager_field_address"             property="address"             class="input-block-level"             additionalattributes="{femanager:misc.formvalidationdata(settings:'{settings}',fieldname:'address')}"             additionalattributes="{ng-model: 'address'}"             placeholder="{f:translate(key: 'tx_femanager_domain_model_user.address')}{f:if(condition:{femanager:misc.isrequiredfield(fieldname: 'address', actionname: actionname)} == 1)->f:then('*')" /> </div> 

but got textbox following placeholder:

adresse{f:if(condition:1 == 1)->f:then('*') 

{f:if(condition:{femanager:misc.isrequiredfield(fieldname: 'address', actionname: actionname)} == 1)->f:then('*') 

that's not valid fluid expression. because of that, fluid interprets can (which inner femanager:misc.isrequiredfield viewhelper, renders 1 or more true).

there 2 issues here:

1. when using f:if viewhelper in inline notation, supply then value argument viewhelper.

   example (simplified):

   {f:if(condition: somevariable, then: '*')} 

2. when using viewhelper in condition argument of f:if viewhelper, needs in string variable:

   example:

   {f:if(condition: "{femanager:misc.isrequiredfield(...)}", then: '*')}
