Please explain the steps to achieve adding custom button next to help link options in footer page in Sugar CRM Version 10.2
i.e., Append new View to Footer layout's list of components
Please refer the below link for adding button in footer.
As per reference : we created viewdefs, but Custom button not displayed in the footer page.
and identified that this button present outside of the <footer></footer> tag.
$viewdefs['base']['layout']['footer']['components'] = array ( 'view' => 'footer-greet-button', );
As of 10.2, the footer is structured a bit differently. It now has a <footer> element within the <div id="footer /> element. So, your existing viewdef is adding the view to the original <div id="footer" /> but the <footer> element is the one that is actually positioned on the bottom of the screen. So, that element is broken into 2 new components:
So, you need to change your references (and directory name) to one of those new values. If you want the button to display on the right side with the help button et al, use:
$viewdefs['base']['layout']['footer-buttons']['components'] = array ( 'view' => 'your-view-name', );
Then be sure to put your layout file in custom/Extension/application/Ext/clients/base/layouts/footer-buttons
