Power App generating PDF with duplicate data from htmlText control

Posted on by sudosaurus 1,599 Super User 2024 Season 1

Hello,

I have built an app that connects to multiple SharePoint lists - these are all served up into galleries and all connect really well in the app to the point that it functions as intended.


On the cases screen, we have a list of buildings in the left side gallery. On the Top right we have a form control that has fields for the building that shows data when a building from the buildings gallery is selected.
On the bottom right we have a list of topics - using the New topic button takes you to another screen where you can create new topics - these are linked to the building.

sudosaurus_0-1699558655432.png
As said above, here we have the other screen where we can view an existing selected topic (from the above screen) or create a new topic. On the top right, we have a list of Subtopics which are associated with each topic and the same building. On the bottom right, we can view the Subtopic information, which includes the Subtopic, Subtopic Breakdown, RAG Status, Argument and Evidence. Makes sense so far??

Back on the Cases screen where we had the list of buildings on the left you will have seen the 'Create PDF' button:

sudosaurus_2-1699559087191.png

When selected, this starts off the process that will ultimately generate a PDF file via Power Automate.

The OnSelect property of the 'Create PDF' button is set to:

// Set your variables first
Set(varItem, ThisItem);
Set(varBuildingPhoto, LookUp(BuildingPhotos, Title = ThisItem.spBuilding).'Link to item');
Set(varBuildingPhotoID, LookUp(BuildingPhotos, Title = ThisItem.spBuilding).ID);

// Data collection and ClearCollect statements go here

// THIS INCLUDES ALL THE TOPIC HEADERS
ClearCollect(colSubtopics1, Distinct(Filter(SubtopicArgEvi_1,Building=varItem.spBuilding),Topic));

// THIS IS THE DISTINCT COLLECTION OF ORDER OF TOPICS
ClearCollect(colSubtopics, ForAll(Sequence(CountRows(colSubtopics1)), Patch(Last(FirstN(colSubtopics1,Value)),{Order:Value})));

ClearCollect(colTempAllSubtopics, AddColumns(Filter(SubtopicArgEvi_1,Building=varItem.spBuilding),"TopicOrder",0,"SubtopicOrder",0));
Clear(colTempAllSubtopicsB);
ForAll(colTempAllSubtopics, Collect(colTempAllSubtopicsB, {
 Top: colTempAllSubtopics[@Topic], 
 SubTop: colTempAllSubtopics[@Subtopic] & " - " & colTempAllSubtopics[@'Subtopic Breakdown'],
 Arg: colTempAllSubtopics[@Argument],
 Evid: colTempAllSubtopics[@Evidence],
 TopOrder: LookUp(colSubtopics,Value=colTempAllSubtopics[@Topic]).Order+2
}));

Clear(colAllSubtopics);

 Collect(colAllSubtopics, ForAll(Sequence(CountRows(Filter(colTempAllSubtopicsB, TopOrder=3)), 3.1, 0.1), Patch(Last(FirstN(Filter(colTempAllSubtopicsB, TopOrder=3), Value)), {SubTopOrder: RoundUp(Value, 2)})));
 Collect(colAllSubtopics, ForAll(Sequence(CountRows(Filter(colTempAllSubtopicsB, TopOrder=4)), 4.1, 0.1), Patch(Last(FirstN(Filter(colTempAllSubtopicsB, TopOrder=4), Value)), {SubTopOrder: RoundUp(Value, 2)})));
 Collect(colAllSubtopics, ForAll(Sequence(CountRows(Filter(colTempAllSubtopicsB, TopOrder=5)), 5.1, 0.1), Patch(Last(FirstN(Filter(colTempAllSubtopicsB, TopOrder=5), Value)), {SubTopOrder: RoundUp(Value, 2)})));
 Collect(colAllSubtopics, ForAll(Sequence(CountRows(Filter(colTempAllSubtopicsB, TopOrder=6)), 6.1, 0.1), Patch(Last(FirstN(Filter(colTempAllSubtopicsB, TopOrder=6), Value)), {SubTopOrder: RoundUp(Value, 2)})));
 Collect(colAllSubtopics, ForAll(Sequence(CountRows(Filter(colTempAllSubtopicsB, TopOrder=7)), 7.1, 0.1), Patch(Last(FirstN(Filter(colTempAllSubtopicsB, TopOrder=7), Value)), {SubTopOrder: RoundUp(Value, 2)})));
 Collect(colAllSubtopics, ForAll(Sequence(CountRows(Filter(colTempAllSubtopicsB, TopOrder=8)), 8.1, 0.1), Patch(Last(FirstN(Filter(colTempAllSubtopicsB, TopOrder=8), Value)), {SubTopOrder: RoundUp(Value, 2)})));
 Collect(colAllSubtopics, ForAll(Sequence(CountRows(Filter(colTempAllSubtopicsB, TopOrder=9)), 9.1, 0.1), Patch(Last(FirstN(Filter(colTempAllSubtopicsB, TopOrder=9), Value)), {SubTopOrder: RoundUp(Value, 2)})));
 Collect(colAllSubtopics, ForAll(Sequence(CountRows(Filter(colTempAllSubtopicsB, TopOrder=10)), 10.1, 0.1), Patch(Last(FirstN(Filter(colTempAllSubtopicsB, TopOrder=10), Value)), {SubTopOrder: RoundUp(Value, 2)})));

UpdateContext({IsLoading: true})

Where UpdateContext({IsLoading: true}) will display a modal dialog - which in this case is a set of controls in a container with a drop shadow to give the appearance of a modal dialog:

sudosaurus_4-1699559279259.png

This modal dialog is a combo of a spinner svg and a timer that counts down from 60,000 milliseconds.


The OnTimerStart property is set to the following: (and allows the above collections to collect data from the various data sources to avoid data being missing from the generated PDF file - this was previously happening and hence why I implemented the timer functionality)

// Trigger the workflow when data is ready
'BSC-PowerApps-v2'.Run(htmlBody_1.HtmlText, varBuildingPhoto, Now(), varBuildingPhotoID, htmlBody_2.HtmlText, htmlBody_3.HtmlText, varItem.ID;)

The OnTimerEnd property is set to the following:

Refresh(DocData);
Set(IsLoading, false); // This will hide the spinner
UpdateContext({IsLoading: false})

 

It's worth noting what the backend code is used for in the three htmlBody htmlText controls in the app - as these are outputting the main HTML static template as well as dynamic information from the datasources/collections into the PDF:

 

varBody1 / htmlBody_1

<h2><font color=blue>BUILDING SAFETY CASE REPORT HEADINGS</font></h2>

Now it's worth noting that the issue seems to be with varBody3 / htmlBody_3 as the data is displayed correctly in the Outputs of the Power Automate flow trigger - PowerApps (V2).

Here's an example of a recent output:

and in the PDF this repeating bit of data displays as this:

sudosaurus_5-1699560150039.png

There's no need to display the Power Automate workflow as the data is being processed incorrectly in the app and outputted in an incorrect way in the initial flow trigger.

 

I appreciate all of this is a longshot however I've tried to detail everything as much as I can.

 

Appreciate any help with this.

 

Thanks!
