Invalid reference to Oracle Forms object

In Oracle Forms, many procedures and functions need a reference to an object (blocks, itens, alerts...). Unfortunately, the only way to pass a reference to an object is using a VARCHAR2 variable and these references are not checked by the compiler.

Currently this rule checks the following methods:

Alert builtins:

• FIND_ALERT
• SET_ALERT_BUTTON_PROPERTY
• SET_ALERT_PROPERTY
• SHOW_ALERT

Block builtins:

• FIND_BLOCK
• GET_BLOCK_PROPERTY
• GO_BLOCK
• SET_BLOCK_PROPERTY

Item builtins:

• CHECKBOX_CHECKED
• CONVERT_OTHER_VALUE
• DISPLAY_ITEM
• FIND_ITEM
• GET_ITEM_INSTANCE_PROPERTY
• GET_ITEM_PROPERTY
• GET_RADIO_BUTTON_PROPERTY
• GO_ITEM
• IMAGE_SCROLL
• IMAGE_ZOOM
• PLAY_SOUND
• READ_IMAGE_FILE
• READ_SOUND_FILE
• RECALCULATE
• SET_ITEM_INSTANCE_PROPERTY
• SET_ITEM_PROPERTY
• SET_RADIO_BUTTON_PROPERTY
• WRITE_IMAGE_FILE
• WRITE_SOUND_FILE

LOV builtins:

• FIND_LOV
• GET_LOV_PROPERTY
• SET_LOV_COLUMN_PROPERTY
• SET_LOV_PROPERTY
• SHOW_LOV

Note: this rule is automatically disabled when the project's sonar.plsql.forms.metadata is not specified.
