How to add an extra custom button to a Share form

[pkanuri]

I have been trying , in vain, to add a "Preview" button to my share form.
After making changes to the share-config-custom.xml I did these things:

1. Edit the form.lib.ftl

   Here is what I added to the renderFormButtons macro
  
   <#if form.showPreviewButton?? && form.showPreviewButton>
         <input id="${formId}-preview" type="button" value="${msg("form.button.cancel.label")}" />
   </#if>
  
  
2. Edit my xml file in the ../site-data/template-instances folder
   
   I used <showPreviewButton>true</showPreviewButton> to be able to display the button .

   Extract:
   
   <component>
         <region-id>create-ediscovery-search-request-content</region-id>
         <url>/components/form?mimeType=text/html&amp;destination=${destination}&amp;formId=ediscoverysearch</url>
         <properties>
            <itemKind>type</itemKind>
            <itemId>cs:ediscoverysearch</itemId>
            <mode>create</mode>
            <submitType>json</submitType>
            <showCaption>true</showCaption>
            <showCancelButton>true</showCancelButton>
         <showResetButton>true</showResetButton>
         <showPreviewButton>true</showPreviewButton> 
      </properties>
      </component>  
    
    
     But still the button does not appear in my form.
     Am I missing anything ? Or is it that one cannot declare buttons other than the predefined
     ones like (submit, reset, cancel)?
    
     Please advise.

Hi,

To do this you need to make changes to org.alfresco.web.scripts.forms.FormUIGet by overriding it.
In this class you need to hande you new parameter and set that to form, so you can use it in ftl.
like:

formUIModel.put(MODEL_SHOW_PREVIEW_BUTTON, discoverBooleanParam(context, MODEL_SHOW_PREVIEW_BUTTON));‍
