Topic: datatable firing again
datatable page change should not fire again.
datatable page change triggers pagechanged event again. Also pageInfo.page restting to zero,
async pageChanged(pageInfo: MdbPaginationChange) {
console.log(pageInfo)
if (pageInfo.page == 0) {
this.companies = await this.companyService.getInitialRows(pageInfo);
}
else
if (pageInfo.page > this.companyService.lastPageNumber()) {
this.companies = await this.companyService.getNextRows(pageInfo);
}
else
if (pageInfo.page < this.companyService.lastPageNumber()) {
this.companies = await this.companyService.getPreviousRows(pageInfo);
}
}
companyservice.ts:
async getNextRows(pageInfo:any) {
if (!this.lastVisible) return [];
this.lastPageNumber.set(pageInfo.page);
const companiesCollection = collection(this.db, 'lmscompanies');
const q = query(
companiesCollection,
orderBy('companyName'),
startAfter(this.lastVisible),
limit(pageInfo.entries)
);
const querySnapshot = await getDocs(q);
if(querySnapshot.size==0)
return []
this.currentDocs = querySnapshot.docs;
this.firstVisible = querySnapshot.docs[0];
this.lastVisible = querySnapshot.docs[querySnapshot.docs.length - 1];
return this.currentDocs.map(doc => doc.data());
}

{{ header }} Actions {{ data.companyName }} {{ data.companyType }}>
@ViewChild('table') table!: MdbTableDirective; tableEntries = 3;
headers = ['Company Name', 'Company Type'];
In companyservice I have a signal named lastPageNumber and I set it and use that to call one of the 3 methods: getInitialRows, getNextRows, getPreviousRows. once the correct method is called the data is populated but then the pageChanged is called again and again and the page number is set back to zero.

Do you modify or use any
mdbTabledirective ormdb-table-paginationcomponent inputs/methods in these 3 method you mentioned?Could you please edit your first post and provide a simple HTML and TS code that we could use to reproduce this problem on our end? Based on the given information it is difficult to determine what exactly changes in our component and why the event is triggered again.
