NullReferenceException in Version 2014.05.19

[PJoyeux]

Hi,

I have switched from version "2014.02.28" to version "2014.05.19" and a report that runs perfectly under the old version now crashes in the new version...

I know it is very difficult to test the report without data but the crash happens in you library and I hope you can help me find the source of this issue.

I have added the report, the stacktrace and other informations.

Please come back to me ASAP...

THANKS!

Hello,

We couldn't reproduce this bug.

Can you please send us a test data or sample project with simple report which reproduce the issue for analysis.

Thank you.

I was afraid you would answer this...
I just can't send you corresponding data, sorry. It's just too complex...

Isn't there any hint you could give me after analyzing the StackTrace? It's a null-pointer exception while rendering a "StiSimpleText" when I read the stack-correctly. What could be a theoretical way to stumble upon a null-pointer there?

And what changes have beend made since "2014.02.28" that could lead to this? Has the rendering of "StiSimpleText" been altered somehow??

I will try to remove controls from the report one after the other until it works, maybe that will help me find the culprit...

Hi,

I was able to locate the problem. Anaylizing the stacktrace it was clear that the problem was a control in the footerband. I analyzed the band and found the culprits: 3 RichText-Fields that were empty.

After inserting a dummy text in them and then deleting the text again the report printed without problems...

In the XML-Kode BEFORE I made the changes the RichtText-Controls looked like this:

Code: Select all

            <RichText10 Ref="147" type="Stimulsoft.Report.Components.StiRichText" isKey="true">
              <BackColor>Transparent</BackColor>
              <Border>All;Black;1;Solid;False;4;Black</Border>
              <ClientRectangle>6.4,1.6,0.8,0.8</ClientRectangle>
              <Conditions isList="true" count="0" />
              <DataColumn />
              <Guid>763fe19afc3f48058b726b0a207b686b</Guid>
              <Margins>0,0,0,0</Margins>
              <Name>RichText10</Name>
              <Page isRef="40" />
              <Parent isRef="113" />
            </RichText10>

After I opened the Control, inserted some Text, closed the controls, then reopened it, cleared the text completely and closed again the controls now looked like this:

Code: Select all

            <RichText10 Ref="148" type="Stimulsoft.Report.Components.StiRichText" isKey="true">
              <BackColor>Transparent</BackColor>
              <Border>All;Black;1;Solid;False;4;Black</Border>
              <ClientRectangle>6.4,1.6,0.8,0.8</ClientRectangle>
              <Conditions isList="true" count="0" />
              <DataColumn />
              <Guid>763fe19afc3f48058b726b0a207b686b</Guid>
              <Margins>0,0,0,0</Margins>
              <Name>RichText10</Name>
              <Page isRef="41" />
              <Parent isRef="114" />

            </RichText10>

There's a new Tag "<Text>" that was missing in the first version. Maybe this was the problem since the error was a NullPointerException...

Anyway, my problem is resolved now, but you might want to investigate this...

Cheers,

Hello.

Thank you for the description.
We will make an investigation and let you know about results.

Thank you.

Hello,

The issue is fixed, will be available in the next prerelease build.
For current version you need set the FullConvertExpression property to true.

Thank you.
