Hi,

In the glamour debugger that we use in moose we are now having the following problem:

��- the selection of a PluggableTextMorph is, quite randomly , changed during styling.

If I revert the fix for��issue 15240��then it works ok.

Also if I change in SHTextStyler>>#styleInBackgroundProcess: ��from

sem waitTimeoutSeconds: 5.

view ifNotNil: [ view stylerStyledInBackground: text ]��

to:

(sem waitTimeoutSeconds: 5) ifFalse: [��

view ifNotNil: [ view stylerStyledInBackground: text ] ]

it works ok. In the second snippet we only do the styling if the styler completed.

If I look at the senders of��styleInBackgroundProcess: there is another strange issue.

First��PluggableTextMorph>>#setText: calls either��style: or��styleInBackgroundProcess:, depending in the size of the text.

Then,��PluggableTextMorph>>#setText: calls��PluggableTextMorph>>#setTextBasic:, which calls PluggableTextMorph>>#hasUnacceptedEdits: which in turn

calls again styleInBackgroundProcess:.��

So when you set the text if the size of the text is small Shout will try to style the text with and without a background process. If you call hasUnacceptedEdits:��

manually when initializing the morph then three processes will be started for doing the styling.

Removing the calls to styleInBackgroundProcess: from PluggableTextMorph>>#hasUnacceptedEdits: ��and PluggableTextMorph>>#basicHasUnacceptedEdits:.

also solves the problem with the changing selection.��

Cheers,

Andrei
