> As already communicated via the [mailing
> list|https://lists.apache.org/thread/2vo7h5tfkgr494qqjsffmyrc3g759bt7], I am
> opening a ticket as requested for the following reason:
> Since version 22.01, but also on the trunk, there is a problem when listing
> timesheets using the form "ListFindTimeSheet" in
> [https://github.com/apache/ofbiz-plugins/blob/trunk/projectmgr/widget/forms/TimeSheetForms.xml].
> When calling a screen that embeds this form, a NullPointerException is
> displayed in the table in the "set to complete" column if the row to be
> displayed is a TimeSheet that has already been completed.
> If I completely stupidly replace "{{{}?complete:""}{}}}" with
> "{{{}?complete:"exists"}{}}}" in row 134 and 148, the error disappears and a
> hyperlink button with the text "exists" appears. I suspect that there has
> been a change that causes the empty string """" to cause a
> NullPointerException at some point.
>
> I looked at the code you linked and realized that I expressed myself poorly.
> I don't think that changes at this point will cause problems. I rather think
> that there might have been changes in the rendering of the forms, because in
> OFBiz 17.x and 18.x the TimeSheets were still listed correctly and the code
> there also uses the empty strings (""). Possibly these empty strings are now
> becoming NullPointerExceptions due to a code change to the rendering.
>
> The exception informs about MacroFormRenderer:
> {{null at
> org.apache.ofbiz.widget.renderer.macro.MacroFormRenderer.makeHyperlinkByType(MacroFormRenderer.java:2918)
> ~[ofbiz.jar:?]}}
>
> Maybe the creation of the anchorElement fails because of this empty string,
> because the context is empty.
> {{final element anchorElement =
> WidgetWorker.makeHiddenFormLinkAnchorElement(linkStyle,}}
> {{ encodedDescription, confirmation, modelFormField,
> request, context);}}
> {\{writer.append(anchorElement.outerHtml()); }}<-- NullPointerException
