>
> Key: CAY-2680
> URL: https://issues.apache.org/jira/browse/CAY-2680
> Project: Cayenne
> Issue Type: Bug
> Components: Modeler
> Affects Versions: 4.1
> Reporter: Stefan S.
> Assignee: Nikita Timofeev
> Priority: Minor
> Fix For: 4.1.1, 4.2.M2
>
> Attachments: cayenne_modeler_text_adapter_patch.diff
>
>
> Observation:
> Several (single line) text fields in Modeler forget changes or insertions of
> text if the user switches to a different panel or tab without explicitly
> leaving (bluring) the text field.
>
> Expectation:
> Text changes shall be kept also in those cases.
>
> Background:
> It hit me several times, when, e.g. walking through a list of entities to add
> comments or modify other texts, that the changes are dismissed due to
> switching to the next entity or a different 'area' of the application. To
> keep the changes, it is necessary to click onto a different UI element within
> the same panel. It seems that changes of single line texts are 'taken over'
> only on 'focus lost' event, which are not fired in the described cases.
>
> As a simple solution, I defaulted 'checkOnTyping' to 'true' in the standard
> constructor of
> {code:java}
> org.apache.cayenne.modeler.util.TextAdapter
> {code}
> which is more a quick hack, since it might not cover all relevant instances
> and introduces some potential processing overhead when typing. A better
> approach would probably be to trigger the commit of changed texts in
> listeners of appropriate events. Nevertheless no negative impact to
> performance was observed using this approach.
> The attached patch provides this change AND the propagation of constructor
> arguments, which have originally been dismissed and replaced by hardcode
> values.
