 Description   

1. it is possible to create web scenarios for templates - probably should not be possible;

2. deleting an application used in such a web scenario results in undefined variable errors :

Undefined variable: host[/usr/local/apache2/htdocs/trunk/include/hosts.inc.php:1394]
Undefined variable: app[/usr/local/apache2/htdocs/trunk/include/hosts.inc.php:1394]
Application ":" used by item "Download speed for step 'df' of scenario 'zz'"
Application "Template_Linux:zz" used by scenario "zz"
[ CApplication::delete ] Cannot delete application

DEV branch: ZBX-3137

Removed templates from host menus in web scenarios;
Button "Create scenario" is now shown disabled when no host is selected with additional hint.

Since it's not possible to use template applications in scenarios, bug is not actual anymore

For 1.8: ZBX-3137-1.8

Seems that "Undefined variable" is still present when trying to delete host application used in scenario.

Changes made:

  • When deleting a template, that has an app used in web scenario, the app is unlinked but not deleted and warning is shown to the user.
  • Template app can't be deleted if it is used by web scenario
  • Some UI improvements

Merged: branches/1.8 15204

Errors still exist. Steps to reproduce:

(1) Create application A on host H.
(2) Create scenario on H in application A.
(3) Create template T1.
(4) Create template T2 and link that to template T1.
(5) Create application A in template T2.
(6) Link template T1 to host H.
(7) Delete application A from template T2.
(8) Go to applications for host H.
(9) Observe scenario-application.png.

Also, while according to the new logic application A should stay on host H after step (7), it should be removed from template T1.

Fixed for 1.8. For trunk this one is fixed in another issue by Aleksei.
