Show request form in read only mode on the portal

[Bottin Jean-Francois]

When you use the "Custom Request Forms" extension, and you try to allow users to see the form they filled out during their request, it will be reset if a comment is recorded on the ticket.

After our analysis, iTop does not provide for read-only display of fieldsets as standard, unlike other field types. At registration, it tries to update the ticket with the editable content which is non-existent, and therefore empties the form.

We propose the following modification on the core side to allow this read-only display :
in sourcesrenderer/bootstrapfieldrendererbssubformfieldrenderer.class.inc.php, at the end of the render function :

add >>                     if (!$this->oField->GetReadOnly())
add >>                {
                        $sFieldSetOptions = json_encode($aFieldSetOptions);
                        $oOutput->AddJs(
<<<EOF
                        $("#fieldset_{$this->oField->GetGlobalId()}").field_set($sFieldSetOptions);
                        $("[data-field-id='{$this->oField->GetId()}'][data-form-path='{$this->oField->GetFormPath()}']").subform_field({field_set: $("#fieldset_{$this->oField->GetGlobalId()}")});
EOF
                                );
add >>                }
add >>                else
add >>                {
add >>                        $sFieldSetOptions = json_encode($aFieldSetOptions);
add >>                        $oOutput->AddJs(
add >><<<EOF
add >>                        $("#fieldset_{$this->oField->GetGlobalId()}").field_set($sFieldSetOptions);
add >>EOF
add >>                                );
add >>                }
                return $oOutput;
        }
