Some rules conditions for 7.x cannot use it.

[barami]

For drupal 7.x

When using og with rules, og provides rules components.
Also og provides rules conditions.

But some rules conditions like 'Entity is group' and 'Entity is group content' is useless for rules.
It always failed to validate on rules ui.
When search a solutions found on community, answer is that use an 'Entity has field' condition.

It seems that it is the condition to check whether entity is group or group content.
Those rules conditions are required entity variable. But rules ui reject when set entity from data selector.

This is logically contradictory rules condition.
